is (-1,4), (5,7), (-2,7), (-1,8) a function?

OpenStudy (amistre64):

if i give you a -1, what would you give me back?

OpenStudy (anonymous):

how do you determine if it is?

OpenStudy (amistre64):

a function can only give you one thing; look at the -1 inputs, what do we get back as outputs? are they the same?
