Write f x 4x 8 f x 4 x 8 as an equation y 4x 8 y 4 x 8 Interchange the variables x 4y 8 x 4 y 8 Solve for y y Tap for more steps y x 4 2 y x 4 2 To find f 1 8 we need to find the input of f that corresponds to an output of 8 This is because if f 1 8 x then by definition of inverses f x 8
The inverse is usually shown by putting a little 1 after the function name like this f 1 y We say f inverse of y So the inverse of f x 2x 3 is written f 1 y y 3 2 I also used y instead of x to show that we are In a function f x or y represents the output and x represents the input To find the inverse of a function you switch the inputs and the outputs Example Let s take f x 4x 3 2x 5 which is one
