Question

Which of the following is the vertex of the quadratic equation y = –4(x + 6)2 + 2?


(–6, 2)
(6, –2)
(6, 2)
(–6, –2)

Answer 1

(-6,2)

Answer 2

y = a(x – h)^2 + k

Answer 3

(h,k) is your vertex

Answer 4

and since the 6 is in parenthesis you change its sign to negative

Answer 5

the 2 is not so it does not change

Answer 6

hence (-6,2)
