if x is repeated it's NOT a function :) @.PatrickStar.

OpenStudy (anonymous):

For me this is due tommorow so

OpenStudy (anonymous):

What does that mean??

OpenStudy (anonymous):

if there are two of the same number in the x value it is not a function

OpenStudy (godlovesme):

if u look at A there is two -7's right? that's repeated @.PatrickStar.

OpenStudy (anonymous):

So B..

OpenStudy (anonymous):

no

OpenStudy (anonymous):

Nheres not repeated numbers

OpenStudy (godlovesme):

A -7 is used twice

OpenStudy (anonymous):

so it is not B that is a function

OpenStudy (anonymous):

D

OpenStudy (godlovesme):

what are the x values for D ? @.PatrickStar.

OpenStudy (anonymous):

-7 -3 0 1

OpenStudy (godlovesme):

any number used more than once or repeated?

OpenStudy (anonymous):

None of the numbers are used twice
