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

Yes

No

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

Yes

No

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

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

Does the set of ordered pairs represent a function?

Yes

No

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

Does the set of ordered pairs represent a function?

Yes

No

Does the set of ordered pairs represent a function?

Yes

No

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

Yes

No

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!
