What is the inverse of the function f(x) = x + 2?.

Solution:

We will be using the inverse function to solve this

f(x) = x + 2

Replace f(x) with y

y = x + 2

Interchange x and y

x = y + 2

Solve for y

y = (x - 2)

Replace y with f^-1(x).

f^-1(x) = x - 2

Thus, the inverse of the function f(x) = x + 2 is f^-1(x) = x - 2

What is the inverse of the function f(x) = x + 2?

Summary:

The inverse of the function f(x) = x + 2 is f^-1(x) = x - 2
