We can find the formula of an exponential function by using two points on the curve, substituting them into the formula y = abx, and solving the system of two equations in two unknowns. Given a graph or a table of values, we just need to choose two points and use the same method described above.
How do you solve an exponential function?
Steps to Solve Exponential Equations using Logarithms
- Keep the exponential expression by itself on one side of the equation.
- Get the logarithms of both sides of the equation. You can use any bases for logs.
- Solve for the variable. Keep the answer exact or give decimal approximations. ...
Does the table represent an exponential function?
No, the table represents an exponential function. The function is The linear equation with slope m and intercept c is given as follows. The values of x are and . No the table represents an exponential function. The function is Learn more about inverse of the functionhttps://.
What is correct way to add exponential functions?
You can add an exponential trendline as follows:
- Select your data and graph it. You can either use a SCATTER plot Do not use the LINE plot because if you have two columns of data it will graph ...
- Select the curve on the graph itself and then right-click. Click on Add Trendline. ...
- You have an option here as well. ...
- If you are statistically
How to graph and transform an exponential function?
- Press [Y=]. ...
- Enter the given value for f ( x) \displaystyle f\left (x\right) f (x) in the line headed “ Y2= .”

What is the exponential equation of a given data?
The equation for the data may involve 1/2x. So, exponential equation of the given data is 1/2x.
Does data show exponential behavior?
The data do not display exponential behavior, but rather linear behavior.
Can an exponential function resemble a quadratic function?
One method is to observe the shape of the graph. But the graph of an exponential function may resemble part of the graph of a quadratic function.
How To Find The Formula Of An Exponential Function
To find the formula of an exponential function, all we need is two different points on the curve. Once we have those two points, we can substitute each pair into the general formula for an exponential function:
Conclusion
Now you know how to find the formula of an exponential function from two points. You also know how to choose two points from a table or graph, and how to use a shortcut formula to find the base “b”.
