Now g(-2)=0

Answer:

5

Step-by-step explanation:

First you want to find f(-2)

Then whatever f(-2) equal, you plug into g(x) to find g(f(-2))

So first lets find f(-2)

Looking at the f(x) graph. When -2 is inputted ( x value -2 ) the output is 1

So f(-2) = 1

We then plug in 1 into g(x) to find g(f(-2))

Think of it as 1 replacing f(-2) in g(f(-2)) because f(-2) = 1

So g(f(-2)) = g(1)

We then look at the graph g(x)

when 1 is inputted the output is 5

Therefore g(f(-2)) = 5
