Question

Determine the x-intercept points of the function h(x) = (x - 5)(x-6)(x + 4).

A. (-4,0), (5,0) and (6,0)

B. (4,0), (5,0) and (6,0)

C. (-6,0), (-5,0) and (-4,0)

D. (4,0), (-5,0) and (-6,0)​

Answer 1

A.

Explanation:

The x-intercepts are the points where the x value is zero. In this case, to find the "zeros" of the function, set each factor to zero. x-5 -> x=5. x-6 -> x=6. x+4 -> x=-4.
