For graphs, if two points are in the same vertical line, its not a function. For the bubble chart, if an x coordinate points to more than one y coordinate, its not a function, and for just some written out coordinates, if any of the x coordinates repeat, its not a function

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
