Write the inverse function for the function, ƒ(x) = x + 4. then, find the value of ƒ -1(4). type your answers in the box. ƒ -1(x) = x ƒ -1(4) =

 The required values are

Step-by-step explanation:  We are given the following function f(x) :

We are to find the values of and

Let us consider that

So, from equation (i), we get

Substituting x = 4 in the above equation, we get

Thus, the required values are

1/4 because there is 4 grades.
