Question

Which of the following sets represents a function?

{(ordered pair one comma one), (ordered pair two comma one), (ordered pair three comma one), (ordered pair four comma one)}

{(ordered pair one comma one), (ordered pair one comma two), (ordered pair one comma three), (ordered pair one comma four)}

{(ordered pair one comma one), (ordered pair two comma one), (ordered pair two comma two), (ordered pair three comma one)}

{(ordered pair two comma one), (ordered pair two comma two), (ordered pair three comma two), (ordered pair four comma two)}

Answer 1

What makes an ordered pair is that an input cannot have multiple outputs. so (1,1) and (1,2) are not classified as an ordered pair because both are outputs of one. However, multiple inputs can share the same outputs.

think of it like this. A pretty girl most likely will be asked by many boys to a dance, and that's fine, but typically, the girl will not go around asking other boys, if it is a traditional dance. so that being said, ordered pairs can have multiple inputs for an output, but not more than one output per input

And I am aware that there are Sadie Hawkins dances where girls typically ask guys, just in case there was a technicality.

Answer 2

the first one would be the answer, in my opinion.
