Question

How do you find the axis of symmetry if only given points (-6,0) and (2,0)?

Answer 1

`x=-2` is the axis of symmetry.

Explanation:

Assuming that we have a parabola, the axis of symmetry is `x=(r_1+r_2)/2` where `r_1` and `r_2` are the roots (when `y=0`). Here, `r_1=-6`, and `r_2=2`, so the axis of symmetry is when

`x=(-6+2)/2=-2`.
