How do you find the axis of symmetry of the quadratic equation #y = 2(x + 7)^2 – 4#?

Answer 1

Genesis Allen

x = -7

Y is in the vertex form, and the axis of symmetry and the vertex's x-coordinate are both x = -7.

To find the axis of symmetry of the quadratic equation y = 2(x + 7)^2 - 4, you use the formula for the axis of symmetry of a parabola, which is x = -b/2a. In this equation, a = 2 and b = 0. Therefore, the axis of symmetry is x = -0 / (2 * 2) = 0. So, the axis of symmetry is x = -7.
