An inverse function essentially undoes the effects of the original function If f x says to multiply by 2 and then add 1 then the inverse f x will say to subtract 1 and then divide by 2 If you want to think about this graphically f x and its inverse function will be reflections across the line y x Given the graph of a function evaluate its inverse at specific points Find the desired input on the y axis of the given graph Read the inverse function s output from the x axis of the given graph
When the function f turns the apple into a banana Then the inverse function f 1 turns the banana back to the apple Example Using the formulas from above we can start with x 4 f 4 2 4 3 11 We can then use the inverse on the 11 f 1 11 11 3 2 4 And we magically get 4 back again To find the inverse of a function let s first start by writing the function as a y equation so it s a little easier to work with y 4x Next we want to find the inverse
