y = −x^2 + 8
Axis of symmetry?
Answered by Reiny
What is the x value of your vertex ?
Answered by Kelly- TO: REINY
0 is the value of x
Answered by Reiny
so the vertex is (0,8)
and the axis of symmetry is x = 0 , or the y-axis
Answered by TO REINY
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!!
Answered by Reiny
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
