Question

What is the vertex of y=|3x+6|-4 ?

Answer 1

@phi

Answer 2

I would have thought the vertex is where 3x + 6 = 0 or where x = -2

so the vertex is (-2, -4)

Answer 3

a simple "typo" dude

Answer 4

the vertex happens where the stuff inside the | | (absolute value signs) is 0
that means you solve for when
3x+6 = 0
if you know algebra, you would find x=-2 is when 3x+6 is zero

once you know x=-2, solve for y using
y=|3x+6|-4
of course you already know 3x+6 is zero, so this is y= 0-4 or simply y=-4
the (x,y) pair of the vertex is (-2,-4)
