The function f(x) = x+18 is one to one Find an equation for f^-1(x), the inverse function

f^-1(x) = x-18, o=you find it by swapping x and y in the equation y=x+18 and solving for y..... x=y+18, subtract 18 from both sides and you get x-18 = y, that is the inverse function

To get the inverse function of a function, follow these steps: 1. replace f(x) with y. So y = x + 18 2. Switch x and y. So x = y + 18 3. Solve y. So y = x - 18 4. Replace y with f^(-1)(x) = x - 18
