Instructions Use this calculator to find the inverse function for a function you provide showing all the steps Please type in the function expression you want to find the inverse for in box below Enter the function you need to find the So the inverse of 2x 3 is y 3 2 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
For example 4 2 means that 4 is to be raised to the second power Hence 4 2 4 4 16 On the other hand 4 2 represents the additive inverse of 4 2 Thus 4 2 16 It may help to think of x 2 as 1 x You have to use the Lambert W function the inverse of x e x Using this function one can find that the inverse of y x x is x e W ln y
