Question

Which function is represented by the graph

Answer 1

The correct answer is D) f(x) = -lx - 4l

Explanation:

We can tell this since the vertex of an absolute value equation is always at (h, k) using the equation below.

f(x) = alx - hl + k

This would make h = 4 and therefore it would be the x value of the vertex, which is true of the picture.
