Asap help!!!!!! Which relations are functions? Select Function or Not a function for each graph.

Answer 1

1st Graph: Function

3rd Graph: Not a function

4th Graph: Not a function

We can determine if a graph is a function or not using the Vertical Line Test. Since we see that 1 and 2 pass but 3 and 4 pass, 1 and 2 are functions while 3 and 4 are not.
