Then complete this assignment.

Question 1

1.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 2

2.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 3

3.

Is the graph below a function?
(Use the vertical line test) (Hint: if the vertical line overlaps everywhere then x would have many y-values) Below you can see that 'x=6' has infinite 'y-values' so it would not be a function!

Yes

No

Question 4

4.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 5

5.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 6

6.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 7

7.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 8

8.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 9

9.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 10

10.

Is the graph below a function? (Use the vertical line test)

Yes

No

Question 11

11.

Does the set of ordered pairs represent a function? (If 1 x-value has more than 1 corresponding y-value then it is not a function; If this is the case then it would also fail the vertical line test)

Yes

No

Question 12

12.

Does the set of ordered pairs represent a function?

Yes

No

Question 13

13.

Does the set of ordered pairs represent a function? (If 1 x-value has only 1 corresponding y-value then it is a function; If this is the case then it would Pass the vertical line test)

Yes

No

Question 14

14.

Does the set of ordered pairs represent a function?

Yes

No

Question 15

15.

Does the set of ordered pairs represent a function?

Yes

No

Question 16

16.

Does the graph represent a function? (Remember open circles do not include the point and closed (solid) circles do include the point. So, if no solid circles touch the same vertical line then it is a function)

Yes

No

Question 17

17.

Does the graph represent a function?

Yes

No

Question 18

18.

Does the graph represent a function? (Remember open circles do not include the point and closed (solid) circles do include the point. So, if Solid circles do touch the same vertical line then it is Not a function)

Yes

No

Question 19

19.

Does the graph represent a function?

Yes

No

Question 20

20.

Does the graph represent a function?

Yes

No

Question 21

21.

Does the graph represent a function?

Yes

No

Question 22

22.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values!) It's ok to have the same y-values but not the same x-values!

Yes

No

Question 23

23.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values! It's ok to have the same y-values but not the same x-values!)

Yes

No

Question 24

24.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values! It's ok to have the same y-values but not the same x-values!)

Yes

No

Question 25

25.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values! It's ok to have the same y-values but not the same x-values!)

Yes

No

Question 26

26.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values! It's ok to have the same y-values but not the same x-values!)

Yes

No

Question 27

27.

Does the set of ordered pairs represent a function? (Remember you can't have the same x-value with more than 1 y-value. In other words, Functions do not have repeating x-values! It's ok to have the same y-values but not the same x-values!)

Yes

No

Question 28

28.

Which of the following sets Do NOT represent a function?
It's kinda obvious! Just make sure you see why! :) Notice that a function can have the same y-values like in Set B, just not the same x-values!

Set A

Set B

Set C

Question 29

29.

Does the table of values below represent a function?

Yes

No

Question 30

30.

Does the table of values below represent a function?

Yes

No

Question 31

31.

Does the table of values below represent a function?

Yes

No

Question 32

32.

Does the table of values below represent a function?

Yes

No

Question 33

33.

Does the relation below represent a function? (Remember each x-values may only be pointing or 'mapped' to 1 y-value to be considered a Function! Functions may have different x-values pointing or 'mapping' to the same y-values.

Yes

No

Question 34

34.

Does the relation below represent a function? (Remember each x-values may only be pointing or 'mapped' to 1 y-value to be considered a Function! Functions may have different x-values pointing or 'mapping' to the same y-values.

Yes

No

Question 35

35.

Yes

No

Question 36

36.

Does the relation below represent a function? (Remember each x-values may only be pointing or 'mapped' to 1 y-value to be considered a Function!
