Question

What are the x-intercepts of the graph of the function below? y = x^2 + 2x - 15 A. (5, 0) and (-3, 0) B. (-5, 0) and (3, 0) C. (-5, 0) and (-3, 0) D. (5, 0) and (3, 0)

To find the x-intercepts, set y = 0 and solve for x:

x^2 + 2x - 15 = 0

Factor the quadratic equation:

(x + 5)(x - 3) = 0

Set each factor to zero:

x + 5 = 0 → x = -5
x - 3 = 0 → x = 3

So, the x-intercepts are (-5, 0) and (3, 0).

Answer: B. (-5, 0) and (3, 0)
