Question

A parabola intersects at x-axis at x= 2 and x= 6. What is the x-coordinate of the parabolas vertex?

Answer 1

x = 4

Explanation:

The vertex is on the line of symmetry. The zeros are located equidistant from the line of symmetry, which is ...

x = (2 + 6)/2 = 4

The x-coordinate of the vertex is x=4.
