So there can be more thanMoreX-intercept so this is the point where a graph goes through the x-axis. So there can be more than one x-intercept. So it's at every single point where your graph goes through the x-axis.
What are the key features of a linear function?
Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept.
What are the 4 types of functions?
The types of functions can be broadly classified into four types. Based on Element: One to one Function, many to one function, onto function, one to one and onto function, into function.
What are the key features of the graph of the absolute value function?
We see that the graph of the absolute value function 'has a V shape, and it satisfies all of the characteristics listed. Its domain is all real numbers; its range is all real numbers greater than or equal to zero; its graph lies completely above the x-axis; and its graph is symmetric with respect to the y-axis.
How are key features of a linear function identified and interpreted from a graph?
An increasing linear function results in a graph that slants upward from left to right and has a positive slope. A decreasing linear function results in a graph that slants downward from left to right and has a negative slope. A constant linear function results in a graph that is a horizontal line.
What are the 6 basic functions?
Common Functions ReferenceLinear Function: f(x) = mx + b.Square Function: f(x) = x2Cube Function: f(x) = x3Square Root Function: f(x) = √x.Absolute Value Function: f(x) = |x|Reciprocal Function. f(x) = 1/x.
What are the 3 types of functions?
Types of Functions One – one function (Injective function) Many – one function. Onto – function (Surjective Function) Into – function.
What are the 8 types of functions?
The eight types are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal.
How do you determine a linear function?
The linear function is found using the point-slope form....The linear function formulas are:y = mx + b (slope-intercept form)y−y1=m(x−x1) y − y 1 = m ( x − x 1 ) (point-slope form)Ax + By = C (standard form)xa+yb=1 x a + y b = 1 (intercept form)
What are characteristics of linear data?
A Linear data structure have data elements arranged in sequential manner and each member element is connected to its previous and next element. This connection helps to traverse a linear data structure in a single level and in single run. Such data structures are easy to implement as computer memory is also sequential.
Which is a linear function?
A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function.

Sketch a Graph Activity
I created this Sketch a Graph Activity to give my Algebra 2 students much-needed practice with the vocabulary we use to describe the key features of functions. This activity was based off of a problem in Pearson’s (now Savvas) Algebra 2 textbook. Even though the alignment of the textbook to the Oklahoma standards has left …
Key Features of Functions Work Mat
I created this Key Features of Functions Work Mat to use with my Algebra 2 students during our introductory functions unit. We used it to practice concepts including domain, range, increasing and decreasing intervals, positive and negative intervals, and x- and y-intercepts. I printed the Key Features of Functions Work Mats on 11 x 17 …
Roots Solutions Zeros X-Intercepts Posters
I’m here today to share some Roots Solutions Zeros X-Intercepts Posters. Yes, that is a mouthful. Yesterday, I started doing some serious planning for teaching Algebra 2 in less than a month! I’m at a new school that has adopted new textbooks, and I’m not exactly the biggest fan of the chosen Algebra 2 book. …
Graphing and Describing Functions Worksheet
I created this graphing functions worksheet to wrap up our unit on parent functions. I wanted them to synthesize all of the information we had learned about parent functions and describing graphs. Students received 6 of these papers and 6 functions to complete the questions about. One equation per parent function. Free Download of Graphing …
Describing Characteristics of Graphs Foldable
One of the main thing my students need to be able to do on their Algebra 2 EOI is to describe graphs. This describing characteristics of graphs foldable is an attempt to introduce my students to the concepts of x-intercepts, y-intercepts, relative maximums, relative minimums, increasing intervals, decreasing intervals, roots, solutions, and zeros.
Characteristics of Graphs & Functions Foldable
I created this Characteristics of Graphs & Functions Foldable recently. After doing domain and range with my Algebra 2 class, my next goal was for students to be able to recognize x-intercepts, y-intercepts, maximum and minimum values, and vertical and horizontal asymptotes.
Domain and Range
x-intercepts and y-intercepts
- x-intercept : 1. This is where the graph crosses the x-axis. 2. To find it algebraically, set y = 0. 3. Have many names : 1. x-intercept 2. Roots 3. Zeros Example : y-intercept : 1. This is where the graph crosses the y-axis. 2. To find it algebraically, set x = 0. Example :
Positive and Negative Intervals
- Positive Interval : In the diagram above, the graph of the function is above the x-axis in the following intervals. (-3, -1) and (2, 4) More precisely, y is positive when x ∈ (-3, -1) and (2, 4). So, the positive intervals for the above graph are (-3, -1) and (2, 4) Negative Interval : In the diagram above, the graph of the function is below the x-axis in the following intervals. (-∞, -3), (-1, 2) and (…
Identifying Intervals of Behavior
- We use interval notation to represent the behavior of the function. The interval measures x-values. The type of behavior describes y-values. In the diagram above, * the graph is increasing in the intervals : (a, b) and (c, d) * the graph is decreasing in the interval : (b, c)
Parent Functions and Their Graphs
- The most basic for a type of function. Determines the general shape of the graph (the end behavior).
Baby Functions
- Look and behave similarly to their parent functions. To get a 'baby' function, add, subtract, multiply, and/or divide parent function by constants. Example : Function Name : Absolute Value Parent Function : f(x) = |x| Baby Function : f(x) = |x - 1|
Identifying Parent Functions
- From equations, identify the most important operation : 1. Special Operations (Absolute Value) 2. Division by x 3. Highest Exponent (this includes square roots and cube roots) Examples : 1. f(x) = x2 + 5x + 6 2. f(x) = 3 / (x + 2) 3. f(x) = 3|x| + 5
Maximum (Maxima) and Minimum (Minima) Points
- Maximum Point (Maxima) : Peaks (or hills) are the maximum points. Minimum Point (Minima) : Valleys are the minimum points. Kindly mail your feedback to [email protected] We always appreciate your feedback.
