Answer:
(c) 32
Explanation:
Given a map between x, g(x), and f(g(x)), you want to find f(g(13)).
Using a map
You want the function value that results when 13 is the argument of g(x), and g(x) is the argument of f(x).
Locate the input (13) in the left column of the diagram. Follow the arrow to find g(13) = 16. Follow the arrow again to find f(16) = 32.
f(g(13)) = 32
