Answer:

  (b)  (−2, 0), (−3, 0), (5, 0)

Step-by-step explanation:

The x-intercepts are the points where the factors are zero. The x-value will be the opposite of the constant in the binomial factor.

  x+2 = 0   ⇒   x = -2

  x+3 = 0   ⇒   x = -3

  x-5 = 0   ⇒   x = 5

The x-intercepts are (−2, 0), (−3, 0), (5, 0).

Answer:

(−2, 0), (−3, 0), (5, 0)

Step-by-step explanation:

When using this form of the function to find the x-intercepts, simply invert the signs to get your answer.
