Question

For the function f(x) and g(x) given in the graph. Find f(g(2))

Answer 1

f(g(2)) = 4

Explanation:

find g(2) then substitute the value obtained into f(x)

locate x = 2 on the x- axis, go vertically up to meet g(x) at (2, 5 )

locate x = 5 on the x- axis, go vertically up to meet f(x) at (5, 4 )

then f(g(2)) = 4
