Question

if the vertex of a parabola is (-2, -4), how would you write your axis of symmetry?

x = -2

x = -4

-2

-4

Explanation:

Step1: Recall parabola axis - of - symmetry property

The axis of symmetry of a parabola is a vertical line that passes through its vertex. For a parabola, if the vertex is in the form $(h,k)$, the equation of the axis of symmetry is $x = h$.

Step2: Identify the x - coordinate of the vertex

Given the vertex $(-2,-4)$, the x - coordinate $h=-2$. So the equation of the axis of symmetry is $x=-2$.

Answer:

A. $x = - 2$
