Question

Let g(x)=2x and h(x) =x^2+4. Evaluate (h times g) (-3)

Answer 1

Answer:

h(g(x)) = 36 + 4 = 40

Step-by-step explanation:

Given as,

g(x) = 2 x     and h(x) = x² + 4

Now h(g(x)) = (2 x)² + 4

Or,    h(g(x)) = 4 x² + 4

Again at x = - 3,

       h(g(x)) = 4 (- 3 )² + 4

Hence h(g(x)) = 36 + 4 = 40  Answer
