Question

What is the axis of symmetry for a parabola with x-intercepts (-3, 0) and (7,0)?

Answer 1

`x = 2`

Explanation:

Since the x intercepts both share zero as a y point. We can find the midpoint of the x coordinates to find the axis of symmetry.

`- 3 + 7 = 4`

`(4)/(2) = 2`

so the axis of symmetry is 2.
