Solution

The inverse of a function is found by switching the x and the y (or f(x)) and solving for y.

So, for the function f(x) = x + 23, we start by replacing f(x) with y:

y = x + 23

Next, we switch x and y:

x = y + 23

Then, we solve for y to find the inverse function:

y = x - 23

So, the inverse of the function f(x) = x + 23 is f^-1(x) = x - 23.
