Question

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

a) x
b) y
c) -7
d) 3
e) -3

Answer 1

x = 7

Explanation:

y = (x – 7)^2 – 3

This equation is in vertex form

y = a(x-h)^2 +k

where (h,k) is the vertex

For a vertical parabola, the line of symmetry is x=h

x = 7
