Given ; f (x) = a | x - b | + c .... The the vertex is ( b,c)

In this problem, the vertex is ( - 5, 8 )

For this question you need to draw the graph of f(x). This is a modulus function -ish. (I guess that's what it's called.) I drew the graph and the vertex I got is at the point (-5,8).

Thank you.

The vertex is (-5,8)
