Answer 3

no :/

Answer 4

\[y=x ^{2}-16x+40\]

Answer 5

no ma'am :/

Answer 6

the equation is in standard form, therefore, it is y=x^2+bx+c
divide your b value by two and square it

Answer 7

oh so that means y = (x - 8)^2 + 48

Answer 8

No, once you have your value, square it.

Answer 9

You should get 64

Answer 10

oh so ... y = (x - 16)^2 + 64 ?
