Question

For the Parabolay = (x + 7)2 – 3. the equation for the Line Of Symmetry is

Answer 1

Hello

Explanation:

Axis of symmetry is vertical:

x=-7 (since (-7,-3) is the vertex)

Answer 2

x = -7

Explanation:

y = (x+7)^2 -3

This is in vertex form

y =a(x-h)^2+k where (h,k) is the vertex and the line of symmetry for a vertical parabola is x=h

y = (x- -7)^2 -3

x = -7
