(I),(II) But im not sure what are you asking for im sorry but only (I),(II) can be Equations
Remember that a function has to pass the vertical line test......that is, if we draw any vertical line on a graph, it can only cut that graph at no more than one point
So
I and II are functions ....any vertical line will cut both graphs at only one point
II and IV are not ......a vertical line will cut both at two points

Thanks! That was a super helpful explanation and will come in handy on my Algebra II final next week.
So i was right ty CPhill because english is not my language and i don't understand if this is the question! Thank you!
Adam remember F(x)=y,x1,2,3...=y1 but can't different y be = with the same x this CPhill means'' if we draw any vertical line on a graph, it can only cut that graph at no more than one point''
I hope you pass your exams!
