The red graph above is of the function fx and the blue graph

The red graph above is of the function f(x), and the blue graph is g(x). Use the graphs to compute the following function values. The spacing between each gridline is one unit.
(a) f(g(2)) =  
(b) f(g(-4)) =

Solution

f(g(2)) , g(2) = 4 => f(4) = -1.

f(g(-4)) , g(-4) = 3 => f(3) = 0
