Answer 1

D . (4, 0) and (-1, 0)

Step-by-step explanation:

At the x-intercepts g(x) = 0, therefore we have the equation:

-2(x − 4)(x + 1) = 0

Either x - 4 = 0 or x + 1 = 0

so x = 4 , -1

The x-intercepts are (4, 0) and (-1, 0)

Answer 2

D) (4, 0), (-1, 0)

Step-by-step explanation:

To find the x intercepts, set y value 0

Solving Steps:

⇒ -2(x − 4)(x + 1) = 0

set groups to zero

⇒ -2(x - 4) = 0, x + 1 = 0

change sides

⇒ x = 4, x = -1

Coordinates: (4, 0), (-1, 0)
