Question

6. A quadratic function has a minimum at (6,-2) and an x-intercept at (10,0).

What is the other x-intercept?

Answer 1

(2,0)

Explanation:

The minimum is 4 units from the x intercept on the x axis.

Since this is a quadratic, values on the same y should be equidistant from the min or max on the x axis.

6+4=10

6-4=2

The other x intercept is at (2,0)
