Question

Identify the intercepts of the function ƒ(x) = x2 – 2x – 15. Question 5 options: A) x-intercepts: (3,0) and (–5,0); y-intercept: (0,15) B) x-intercepts: (–3,0) and (5,0); y-intercept: (0,15) C) x-intercepts: (3,0) and (–5,0); y-intercept: (0,–15) D) x-intercepts: (–3,0) and (5,0); y-intercept: (0,–15)

Answer 1

X-intercepts: (-3,0) and (5,0)

Y-intercept: (0,-15)

Explanation:

x^2 - 2x - 15

(x + 3) (x -5)

x +3 = 0

x = -3. (-3, 0)

x - 5 = 0

x = 5. (5, 0)
