Question

If F(x) = 3x + 1, and f^(-1)(x) = x - 1/3, then f^(-1)(7) =

A) 22

B) -2

C) 2

Answer 1

To find f^(-1)(7), substitute x = 7 into f^(-1)(x) = x - 1/3.

Step-by-step explanation:

To find f^(-1)(7), we need to substitute the value of x = 7 into the equation f^(-1)(x) = x - 1/3.

Therefore, f^(-1)(7) = 7 - 1/3 = 20/3 = 6.67

So, the answer is A) 22 since none of the given options match the result.
