Question

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

Answer 1

divide out that 4 and you should end up with it

Answer 2

another way is to find the value of x that makes that inner part go to zero

Answer 3

This is what I did but my answer should only be one
4x-12=0
x=3 that is for x

y=0-3
y=-3

Those are the last two of all I did

Answer 4

3 is correct
