Key Concepts

Inverse Function

An inverse function reverses the operation of the original function, meaning that if the original function takes an input x and produces an output y, the inverse function takes y as an input and returns x. Finding an inverse generally involves solving for x in terms of y and then swapping the roles of x and y.

Reflection Over the Line y = x

The graph of an inverse function is the mirror image of the graph of the original function when reflected across the line y = x. This reflection property is used as a visual test to confirm whether two functions are inverses of each other.

Graphing Functions

Graphing functions involves plotting a set of points that satisfy the equation of the function and connecting them with a line or curve, as appropriate. Careful graphing helps in visualizing the behavior and properties of the function such as its slope, intercepts, and continuity.

Graphing Inverse Functions

Graphing an inverse involves first finding the inverse algebraically, then plotting its points and using the reflection property across the line y = x to ensure accuracy. In many representations, a different line style, such as a dashed line, is used to differentiate the inverse function from the original.
