Inverse Relation of a Graph

  • Choose some points on the given relation (graph).
  • Interchange the x and y coordinates of each point to get new points.
  • Plot all these new points and join them by a curve which gives the graph of the inverse relationship.

To find the inverse of an algebraic relation in terms of x and y, just interchange the variables x and y, and solve the equation for y. For example, to find the inverse of a relation y = x3, interchange x and y and then solve it for y. Then we get x = y3 ⇒ y = x1/3.

What is an Inverse Relationship?

An inverse relationship is one which is the reverse of another or one in which when one variable factor increases, another decreases. The English term inverse is derived from a Latin word that means “turn upside down”; or opposite in some way. It the sort of relationship that appears in many disciplines, including mathematics, economics and finance. A few examples from each of these areas will illustrate how inverse relationships occur and operate. Let us begin with mathematics.

How to tell if a function is a domain or range?

A mathematical function is simply a rule that describes the relationship between ordered pairs, going either from x-values to y-values, in which case it is written y = f (x) or from y-values to x-values and written x = f (y) or y = f -1 (x). The set of values of the variable in brackets is called the domain, while the set of values of the other variable is known as the range. Thus, in y = f (x), the x-values are the domain, while the y-values are the range. Sometimes, a function is described as a machine that takes input – the x-values – and delivers output – the y-values.

What is the relationship between dependent and independent variables?

They entail a link between two variables, where either (i) the dependent and independent variables swap roles, i.e., the dependent variable becomes the independent variable and vice versa; or the dependent variable decreases (increases) as the independent variable increases (decreases).

Is the link between two variables causal?

The link between the two variables may depend on some causal relationship or they may have been paired randomly. Regardless, by virtue of being paired, the x and y values in each pair, and by extension, the two variables which they represent are now in a relationship.

What Does Inverse Correlation Tell You?

Inverse correlation tells you that when one variable is high, the other tends to be low. Correlation analysis can reveal useful information about the relationship between two variables, such as how the stock and bond markets often move in opposite directions.

What is the difference between inverse and negative correlation?

An inverse correlation, also known as negative correlation, is a contrary relationship between two variables such that when the value of one variable is high then the value of the other variable is probably low. For example, with variables A and B, as A has a high value, B has a low value, and as A has a low value, B has a high value.

What is the correlation coefficient of inverse correlation?

In statistical terminology, an inverse correlation is often denoted by the correlation coefficient "r" having a value between -1 and 0, with r = -1 indicating perfect inverse correlation.

What is the most common correlation?

Correlation can be calculated between variables within a set of data to arrive at a numerical result , the most common of which is known as Pearson's r. When r is less than 0, this indicates an inverse correlation. Here is an arithmetic example calculation of Pearson's r, with a result that shows an inverse correlation between two variables.

Why is correlation coefficient important?

The correlation coefficient is often used in a predictive manner to estimate metrics like the risk reduction benefits of portfolio diversification and other important data. If the returns on two different assets are negatively correlated, then they can balance each other out if included in the same portfolio.

How to find correlations?

First, add up all the X values to find SUM (X), add up all the Y values to find SUM (Y) and multiply each X value with its corresponding Y value and sum them to find SUM (X,Y):

Does a negative correlation necessarily imply a causal relationship?

First, the existence of a negative correlation, or positive correlation for that matter, does not necessarily imply a causal relationship. Even though two variables have a very strong inverse correlation, this result by itself does not demonstrate a cause-and-effect relationship between the two.
