Evaluate: g(f(5))
y = f(x)
y = g(x)

Answer:
g(f(5)) = 6
Step-by-step explanation:
Obtain f(5) from the graph of y = f(x)
Locate x = 5 on the x- axis, go vertically up to meet the graph at (5, 4 )
Now evaluate g(4) from the graph of y = g(x)
Locate x = 4 0n the x- axis, go vertically up to meet the graph at (4, 6 )
Then the value of g(f(5)) = 6
