What are the x-intercepts of this quadratic function? g(x) = - 2(x - 4) * (x + 1)

A. (- 4, 0) and (- 1, 0)
B. (4, 0) and (- 1, 0)
C. (- 4, 0) and (1, 0)
D. (4, 0) and (1, 0)

I believe it’s C, but please correct me if I’m wrong!

Hi,

The correct answer is B.

The equation is g(x) = -2(x − 4)(x + 1).

In this equation (x - 4) and (x + 1) are the x-intercepts. In this form (x - 4) and (x + 1) are zeros.

Therefore the x-intercepts are (4,0) and (-1,0).
