Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.

Read values of an inverse function from a graph or a table of the original function.

Learn how to find the inverse of a function and how to graph it in this video. The inverse function swaps the x and y values of the original function, and the graph of this inverse function is a reflection of the …

Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.

Learn how to find the formula of the inverse function of a given function. For example, find the inverse of f(x)=3x+2.
