Question

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

Answer 1

4x+12=0

Answer 2

look at the absolute value expression alone => |4x + 12|
what value for "x" can make that expression = 0?

Answer 3

Wait so which one is it??

Answer 4

dunno, what do you think will make |4x +12| =0? if we set "x" to?

Answer 5

-3

Answer 6

but the plus 3 at the end wouldnt make it 0 it would be 3

Answer 7

\(\bf |4x + 12|\\
|4(\color{red}{-3}) + \color{red}{12}|\\
(\color{red}{-3}, \color{red}{12})\)

is the vertex then

Answer 8

This is the question What is the x-coordinate of the vertex of y = |4x + 12| + 3 ?

Answer 9

hmm, well, just look at the ordered pair
