Question

evaluate: $g(f(4))$

Explanation:

Step1: Find $f(4)$ from the graph

Locate $x=4$ on the $y=f(x)$ graph, the corresponding $y$-value is $-6$. So $f(4) = -6$.

Step2: Find $g(-6)$ from the graph

Locate $x=-6$ on the $y=g(x)$ graph, the corresponding $y$-value is $10$. So $g(f(4))=g(-6)=10$.

Answer:

10
