Question

What is the equation of the axis of symmetry of a parabola if its x-intercepts are –3 and 5?

Answer 1

x = 1

Explanation:

The axis of symmetry is a vertical line and is located at the midpoint of the x- intercepts, thus

x =
`(-3+5)/(2)` =
`(2)/(2)` = 1

That is equation of symmetry is x = 1
