Im not sure I missed class the day this lesson we covered functions so I have no clue what the definition of a function is. I do know that if you draw a vertical line & it touces a line more than one it is not a function....i think

ok, in order for a relation to be a function, no first element (the x-coordinates) can be paired up with two different second elements (y-coordinate). I know, it sounds confusing even to me.
