The function fx x 11 is onetoone Find an equation for f1 x

The function f(x) = x + 11 is one-to-one Find an equation for f^-1 (x). the inverse function f^-1(x) = (Type an expression tor the inverse Use integers or fractions tor any numbers in the expression)

Solution

First, replace with y. This is done to make the rest of the process easier.

step 1 - Replace every x with a y and replace every y with an x.

Solve the equation

y = x +11 (given)

the apply the step 1 and i will get x = y +11

then invrse function is y = x-11
