If f(x) = log2 (x + 1), what is f-1(2)? (2 points)

as you already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

Step-by-step explanation:

This we means to to solve the following equation for b:

since f(b)=2

Write in equivalent exponential form:

Subtract 1 on both sides:

This means

You could actually find the inverse function if you want to then replace input for the inverse with 2.

Your logarithm has base 2 and input (x+1) and output y.

The equivalent exponential form is:

If we solve for x then at the end swap x and y we would have found the inverse function.

Let's do that:

Swap x and y:

The inverse function of our given function is:

Now we need to replace x with 2:
