Question

In which function is x = 2 mapped to 32? A. g(x) =4(x+3)^2-68 B. h(x)=3x C. j(x)=2x-62

Answer 1

a

Explanation:

Answer 2

You have to plug 2 in to all the functions and check.

Let us plug 2 into g(x) and check


`g(x) = 4(x + 3) {}^(2) - 68`


`g(2) = 4(2 + 3) {}^(2) - 68`

`g(2) = 4(5) { }^(2) - 68`

`g(2) = 4 * 25 - 68`

`g(2)=100 \: -68`

`g(2)= \: 32`


The correct answer is A
