Question

Let g(x) = 2x and h(x) = x2 + 4.

Evaluate (h.g)(1).
A. 2
B. 10
C. 4
D. 8

Answer 1

10

Explanation:

Hello,

(h.g)(1)=h(1)*g(1)

h(1)=1+4=5

g(1)=2

so h(1)*g(1)=5*2=10

the correct answer is 10

Answer 2

10

Explanation:

g(x) = 2x

h(x) = x^2 + 4

(h*g)(1)

h(1) = 1^2 +4 = 1+4 = 5

g(1) = 2*2 =2

(h*g)(1) = 5*2 = 10
