Question

Given f(x) = x - 7, solve for f⁻¹(4).

A) 1
B) -1
C) 33
D) 37
E) 19

Answer 1

The solution to finding f⁻¹(4) where f(x) = x - 7 is to set x - 7 equal to 4, and solve for x, which results in x = 11. However, this solution is not present in the given options.

Step-by-step explanation:

To solve for f⁻¹(4), we are looking for the value of x such that f(x) = 4. Given f(x) = x - 7, we can set up x - 7 = 4 and solve for x by adding 7 to both sides of the equation. This gives us x = 11.

Therefore, the value of f⁻¹(4) is 11, which is not listed in the options provided. It seems there might be a mistake with the options given, as none of them match our solution.
