Question

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(1). 2 8 10 4

Answer 1

Hello!

You can solve this by plugging 1 into
`g(x)` and plugging the result into
`h(x)`.


`g(x) = 2x`

`g(1) = 2(1)`

`g(1) = 2`


`h(x) = 2x + 4`

`h(g(1)) = 2(2) + 4`

`h(g(1)) = 4 + 4`

`h(g(1)) = 8`

Answer:
(h ∘ g)(1) = 8
