Respuesta :

There's a trick you can do to figure out if it's a function or not:
      You just draw a line straight up and down; if the line passes the graph twice, it is not a function. 

I'm not too sure what the answer is because I haven't done functions since I was a sophomore, but I think it is C.

Sorry if that's wrong, lol.
