Answer:
Nope, not function
Step-by-step explanation:
If you draw a line down from any point on the line the is graphed (not x and y line), you can see there is two points that intercepts the original line. A function is where when you draw a line through the original line, there will be only one intercepting point. A non-function is when you draw a line down the original line, there will be TWO intercepting line.
