Best ResponseYou've already chosen the best response.0for a relation to be a function for each two elements of it: ex (a,b) (c,d), a must not be equal to c, that is you can't have (a,b) and (a,d) both in the relation(if b=d then (a,b) and (a,d) are equal and they are just one element)

Best ResponseYou've already chosen the best response.0so basically what marks a function is that for each element of a set A it gives element of a set B, it can't give you two different elements ex. you can't have f(a)=b and f(a)=c at the same time unless b=c

Best ResponseYou've already chosen the best response.1you can try plotting the points on your own made graph and use the vertical line test to see if a horizontal hits the plotted points line more than once. If it does the relation is not a function

Best ResponseYou've already chosen the best response.0well, learning what a function, a set, and a relation is, is much better than plotting graphs, it will simplify your life if you're going to learn math.

Best ResponseYou've already chosen the best response.1that is true, but it was just a suggestion lol but go the harder way, you'll learn more.
