1 Four sets of ordered pairs are shown below. a. {(2, -4), (-3, -5), (-3, 3), (-2, 6)}
b. {(5,2), (3, 2), (-1, 2), (3,4)}
C. {(-6, -4), (3, -4), (-2,-4), (5, -4)}
d. {(3, 2), (-3, -2), (3, 6), (8, 2)}
Which set(s) of ordered pairs do NOT represent a function?
A a only
B a and c only
C a, b, and d only
D All of the above

The answer is C. a, b, and d only.

Step-by-step explanation:

A is not a function because -3 has two y like, (-3,-5) and (-3,-3).

B is not a function because like A, it has an x that has more than one y value, like (3,2) and (3,4)

C is a function because all the x values only have one y value, even though there are many x values that contain the same y value but to be a function the x value must not repeat (only if the y value is the same) or have multiple y values for the same x value.

D is not the function because the x value 3 has two different y values, (3,2) and (3,6)

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

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
