WebTo find the inverse of a function, you can use the following steps: 1. In the original equation, replace f (x) with y: to 2. Replace every x in the original equation with a y and every y in the original equation with an x Note: It is much easier to find the inverse of functions that have only one x term. WebLet’s determine if the following graphs are functions. (1) Every x value has a unique y value. This is a function. (2) Though two x values may have the same y value, each x value only has one y value. This is indeed a function. (3) We can see that at least one vertical line has intersects at more than one point with the graph.
