Question

Please help?

1: The x-intercepts of a quadratic function are -3 and 5. What is the equation of its axis of symmetry?

#2: The solutions to a quadratic equation are x = 2 or x = -3. What are the x-intercepts of the related quadratic function?

Answer 1

see explanation

Explanation:

(1)

The axis of symmetry is situated midway between the x- intercepts, thus

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

Equation of axis of symmetry is x = 1 → d

(2)

The x- intercepts of a quadratic are the solutions, thus

x = 2 and x = - 3 → b
