The graph of f(x) = x2 − 3x − 28 is shown. which of the following describes all solutions for f(x)?
a). (−4, 0), (0, −28), (7, 0)
b). (−4, 0), (−1, −24), (0, −28), (3, −28), (7, 0)
c). (x, x2 − 3x − 28) for all real numbers
d). (x, y) for all real numbers

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

hows it hangin lol
