Math Problem Statement

Find f(-4) given the table of values for the inverse function f⁻¹(x).

Solution

To find f(4)f(-4) from the given table of values for f1f^{-1}:

The table shows values of f1(x)f^{-1}(x), which is the inverse of f(x)f(x). We need to recall that if f1(x)=yf^{-1}(x) = y, then f(y)=xf(y) = x. In this problem:

  1. We want f(4)f(-4).
  2. Looking at the table, f1(8)=4f^{-1}(8) = -4.
  3. By the definition of an inverse function, if f1(8)=4f^{-1}(8) = -4, then f(4)=8f(-4) = 8.

So, the answer is: f(4)=8f(-4) = 8
