Question

G(x) = 3x + 4
h(x) = x³ +3
Find (goh)(3)
the “o” represents an open circle

Answer 1

(g ○ h)(3) = 94

Explanation:

to find ( g ○ h)(3) , evaluate h(3) , then substitute the value obtained into g(x)

h(x) = x³ + 3

h(3) = 3³ + 3 = 27 + 3 = 30 , then

g(x) = 3x + 4

g(30) = 3(30) + 4 = 90 + 4 = 94

so (g ○ h )(3) = 94
