Write the inverse function for the function, ƒ(x) = 1/2x + 4. then, find the value of ƒ -1(4). type the answer exactly in this form. ƒ -1(x) = x ƒ -1(4) =

We can get the inverse function by first setting f(x) = y, solving for x, and after that switching y and x. So, let's solve for x:





Then, just plug in 4 for x, and solve:



There you have your answer.
