Math Problem Statement

What is the value of g(f(-4))?

Solution

Let's solve the given problem step by step.

We are asked to find the value of g(f(4))g(f(-4)).

Step 1: Find f(4)f(-4)

From the graph of f(x)f(x) (on the left), we can see that the point where x=4x = -4 corresponds to the y-value of f(x)f(x). The red line at x=4x = -4 reaches f(4)=2f(-4) = 2.

So, we have: f(4)=2f(-4) = 2

Step 2: Find g(f(4))=g(2)g(f(-4)) = g(2)

Now, we need to find g(2)g(2) using the graph of g(x)g(x) (on the right). From the graph of g(x)g(x), we see that at x=2x = 2, the y-value is g(2)=4g(2) = 4.

Thus: g(f(4))=g(2)=4g(f(-4)) = g(2) = 4

Final Answer:

g(f(4))=4g(f(-4)) = 4
