help plz

OpenStudy (anonymous):

With what ?

OpenStudy (anonymous):

OpenStudy (sleepyjess):

Can you tell me what you think?

OpenStudy (anonymous):

yea I think is c or b

OpenStudy (sleepyjess):

A function can only have 1 of each x value. B has 2 of the x value -1. C has 2 of the x value -10. Does that help?

OpenStudy (anonymous):

ok I think so maybe a

OpenStudy (sleepyjess):

Yep, do you know why D is incorrect?

OpenStudy (anonymous):

no not really and why?

OpenStudy (sleepyjess):

If you look at the table for option D, there is -10, -9, -1 and -9. -9 shows up twice so this cannot be a function.
