Question

The roots of a quadratic equation are (1,0) and (-5,0). What is the axis of symmetry?

Answer 1

Explanation:

The axis of symmetry lies exactly halfway between the given x = 1 and x = -5.

The axis of symmetry is x = -2.

The 'halfway' value is also the 'average' of 1 and -5: -4/2, or -2.

The axis of symmetry is x = -2.
