Answer:

1) Function

2) Function

3) Not a Function

Step-by-step explanation:

Using the vertical line test, using a pen, pencil or finger to move it vertically, I determined that 2 of the 3 questions was a function because the last question would not be a function since there are two lines instead of one when doing the test. Hope this helps!

Answer:

First one is a function, second is as well, the third isn't

Step-by-step explanation:

When there are 2 points on a line with the same x it means its not a function like in the last one.
