Question

What is the axis of symmetry of the graph of y = –(x + 3)2 – 6?

Answer 1

**y = –(x + 3)^2 – 6

Answer 2

A. x = 6
B. x = –3
C. x = 1
D. x = –1

Answer 3

y = -x^2 -6x + 9 - 6
y = -x^2 -6x + 3

x vertex : -b/2a
6 / -2 = -3

so x= -3 :)

Answer 4

Thank you ((:

Answer 5

y = –(x + 3)^2 – 6
@Coolsector: when the quadratic is in this form, you can read off the axis of symmetry. It's the number that makes (x+3) zero. i.e. x= -3. Also, quadratic peak (or minimum, depending on the sign) is (-3, -6) where you read off the y value -6.
