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

Answer:

a

Step-by-step explanation:

Answer 2

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

Let us plug 2 into g(x) and check

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

$g(2) = 4(2 + 3) {}^{2} - 68$
$g(2) = 4(5) { }^{2} - 68$
$g(2) = 4 \times 25 - 68$
$g(2)=100 \: -68$
$g(2)= \: 32$


The correct answer is A
