Question

Find the vertex equals the absolute value of the quanity 3x+6 minus 4 of y is

(2, -4)
(-2, 4)
(-2, -4)
(-6, -4)

Answer 1

\[ \large |3x+6|=y-4 \]
???

Answer 2

y in front 3x+6 but everything else right

Answer 3

\[ \large y=|3x+6|-4 \]
??

Answer 4

yes

Answer 5

it can be rewritten into
\[ \large y+4=3|x+2| \]
ok?

Answer 6

ok well what would i do next to do simplify

Answer 7

remember the equation of a parabola:
\[ \large y-k=a(x-h)^2 \]
has vertex \((h,k)\).
it is the same here
the vertex is in (-2,-4)
