Answer 2

what makes the x part go to zero?

Answer 3

x+4 = 0 gives us the axis of symmetry

Answer 4

so x = 0?

Answer 5

lets chk ... does 0+4 = 0 ??? no

Answer 6

no but 4 + -4=0

Answer 7

x + 4 = 0 when x=-4, therefore the axis of symmetry is x=-4

Answer 8

\[\large y = -2~\underbrace{(x + 4)}_{\text{helps define axis of symmetry}}~^2 + 7\]

Answer 9

yes

Answer 10

what do i need to do
