Answer:

How you can tell

Explanation:

A function assigns exactly one output to each input: x/input y/output

How they work: X can not repeat but Y can.

Lets see your problem, there are no inputs repeating and the outputs are fine.

That is a function!

Answer:

To know if it is a function see if there are two of the same x-intercept( which makes a vertical line). If there is,then it is not a function.
