1. Suppose the equation of the axis of symmetry for a quadratic function is x = -3

and one of the x-intercepts is -8.

What is the other x-intercept?


2. If the equation of the axis of symmetry of a quadratic function is x = 0,

and one of the x-intercept is -4, what is the other x-intercept?

Answer 1

Two
===
x=0 is the y axis. So the other x intercept is a mirror image of x = - 4.
x = 4 is the other x value for the intercept.
(4,0) is the other intercept. <<==== answer.

One
===
Axis of symmetry is x = - 3
One of the intercepts is (- 8,0) That is 5 units to the left of (-3,0) so now yo much go 5 units to the right of (-3,0)
That will take you to -3 + 5 = 2
(2,0) is the other intercept <<<<< ===== answer.
