Question

Wendall designs a tower with a height in feet that can be represented by the function T(x) = 9(x + 6.9), where x is the height of the visible space in a standard office. Then, he decides to include an above ground parking garage under the tower. The height of the parking garage can be represented by the function G(x) = 3x.

Answer 1

`G(T(x)) = 27(x + 6.9)`

Explanation:

Given

`T(x) = 9(x + 6.9)`

`G(x) = 3x`

Required [Missing from the question]

G(T(x))

We have:

`G(x) = 3x`

This implies that:

`G(T(x)) = 3(T(x))`

Substitute:
`T(x) = 9(x + 6.9)`

`G(T(x)) = 3[9(x + 6.9)]`

Open bracket

`G(T(x)) = 27(x + 6.9)`
