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

 15) D     16) D         17) D

Step-by-step 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.

correct answers

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
