whpalmer4 · Answer

all of them are relations, right?

whpalmer4 · Answer

a function is a special sort of relation, one where there is only 1 y value for each value of x.

whpalmer4 · Answer

look down the list.  are any of the x values repeated?  If so, do they have different y values?  if you find the same value of x combined with a different value of y, it is not a function.
