can u ask them one by one

anonymous · Answer

Okay in order to solve this you have to know what a function is: A function is a special relationship where each INPUT has ONE OUTPUT. In other words, the first number in each pair can not not have the same second number in their pair.

a is answer

So b

anonymous · Answer

Yes it would be A because if these points were on a line they would not intersect meaning that A is a function. But you CAN NOT give out answers @HARSH123. Code of Conduct: http://openstudy.com/code-of-conduct

I mean if the points were on a GRAPH they would not intersect @Brandonsnider188.
