Question

A quadratic function has one zero (x-intercept) at x = -5 and another zero at x = 3. What is the equation of the axis of symmetry of this function?

Answer 1

x = - 1

Explanation:

The axis of symmetry is a vertical line located at the midpoint of the zeros.

Equation is then

x =
`(-5+3)/(2)` =
`(-2)/(2)` = - 1 , that is x = - 1
