Answer 6

whats the domain

Answer 7

-3, 0, 4, 1

Answer 8

What?

Answer 9

Domain is \(\large{x}\) in \(\large{(x,y)}\)

So the domain would be...

\(\Huge{Domain: -3, 0 ,4, 1}\)

~~~~~~~~~~~~~~~~~~~~~~~~~

You can determine if it is a function as long as \(\large{x}\) is not repeated as well as \(\large{y}\)....

\(\LARGE{{(-3,7), (0,2), (4,0), (1,-1)}}\)

There is no repeat of \(\large{x}\) and no repeat of \(\large{y}\) so this would in fact be a function....

Do you understand this @Abbster2015backup ?
