-12(3x + 7y) = 22
3(12x + 28y) = 88

-36x -84y = -264
36x + 84 y = 264

0 = 0

Which equation represents the function graphed on the coordinate plane? g(x) = |x + 4| – 2 g(x) = |x – 4| – 2 g(x) = |x – 2| – 4

Misha Larkins [42]

Answer:

$g(x)=|x+4|-2$

Step-by-step explanation:

All the absolute value functions given in the option are of the form:

$g(x)=|x-h|+k$ , where (h,k) is the vertex

From your description the absolute value graph has vertex at (-4,-2)

Hence h=-4 and k=-2.

We substitute to get:

$g(x)=|x--4|+-2$

We simplify to get:

$g(x)=|x+4|-2$
