Question

What are the roots of the quadratic function in the graph?

A)-12

B)-4, 3

C)-4,-3

D)-3, 4

Answer 1

D

Explanation:

The roots are where the curve crosses the x-axis. So that's x=-3 and x=4.

Answer D.

Answer 2

D

Explanation:

The roots are the points on the x- axis where the function has a value of zero. That is where the graph crosses the x- axis

The graph crosses the x- axis at x = - 3 and x = 4, hence

Roots of the quadratic function are x = -3, 4 → D
