Question

What is the vertex of the graph of y = –|2x + 4|+ 3?

(–2, –3)

(–2, 3)

(2, –3)

(2, 3)

Answer 1

You could make a simple graph to figure out.

Answer 2

By graphing at different points you can see that the vertex is (-2,3)

Answer 3

The best way of doing it, though, it noting when |2x+4|=0

Answer 4

x=-2

Answer 5

Thanks for your help :) I definitely get it more now

Answer 6

Yea

Answer 7

The graph "turns" because the absolute value stops at 0

Answer 8

It can't go lower than that.

Answer 9

So for these problems it is usually best to note when the absolute value is 0. That is usually an important point to note.
