Question

y = −x^2 + 8
Axis of symmetry?

Answer 1

What is the x value of your vertex ?

Answer 2

0 is the value of x

Answer 3

so the vertex is (0,8)
and the axis of symmetry is x = 0 , or the y-axis

Answer 4

That's what I put and it was marked wrong..it is a two part questions I got (0,8) correct but the axis of symmetry wrong...hmmm thanks!!

Answer 5

I am 100% sure that I am correct
the axis of symmetry is x = 0

For any vertical parabola , (like yours), if the vertex is (p , q), the axis of symmetry is x = p
