Question

What is the x-coordinate of the vertex of y = |4x – 12| – 3 ?

Answer 1

It's basically the x value that makes the part within the absolute value a zero. In other words 4x-12=0 so x=3.

Answer 2

the idea is that you 'flip' the graph upwards from (3,-3) and below.

Answer 3

so its =-3

Answer 4

the question is asking for the x coordinate, not the y, so 3 would be the answer
