Question

The options for the first one. A.4 B.-4 C.0 D.both -4 and 4

the options for the second one. A.3 B.-2 C.2 D.both 2 and -2
the options for the second third. A. x - intercepts B.Zeros of the function C.Roots of the functions D.All of above

Answer 1

Answer: 15) D 16) D 17) D

Explanation:

15) option D

when y = 2, x = -4 and x = +4

16) option D

when y = 0, x = -2 and x = +2

17) option D

when y=0, the x-values are the zeros.

The points are on the x-axis so are the x-intercepts.

The x-values can be found using the Quadratic Formula, which are also called the roots.
