Question

Which statement best explains whether these ordered pairs represent a function (-4,2), (6,7), (-8,3),(9,10),(12,14), (6,9)

Answer 1

These points do NOT represent a function.

In a function, all of the individual inputs only have one output. However, take a look at the input of 6. There are 2 different outputs for the 6. We have a (6, 7) and a (6, 9). This makes the relation not a function.
