@nikato help please?

nikato · Answer

youo know your points are writeen in this format

anonymous · Answer

Okay

nikato · Answer

and are the x's(which is what you put INTO an equation is the domain

and the y's which is what comes OUT is called the range

anonymous · Answer

@nikato so the domain is each first number?

nikato · Answer

correct.
and the range would be the second number(the one after the comma)

anonymous · Answer

@nikato is it a function?

nikato · Answer

hint: a function is when only ONE x matches to exactly one y.
so you can have 2 different x with the same y.
but youu CANT have 2 different y with the same x
