So, on the function, where y=2, x=4. Hope this helps.

An important relationship between a function and its inverse is that they “undo” each other. If f − 1 is the inverse of a function f, then f is the inverse of the function f − 1. In other words, whatever the function f does to x, f − 1 undoes it—and vice-versa. f − 1(f(x)) = x, for all x in the domain of f. and.

3. Switch the variables. Replace x with y and vice versa. The resulting equation is the inverse of the original function. In other words, if we substitute a value for x into our original equation and get an answer, when we substitute that answer into the inverse equation (again for x ), we'll get our original value back!Do it! (or both for practice!) *Note: This is just like ( f o g ) ( x ), but with different notation. STEP 1: Stick a " y " in for the " f (x) ." STEP 2: Switch the x and y.
