    a set of ordered pairs represent a function if there are two such pairs that (a,b) and (a,c), it holds that b=c

    obviously in c) it doesn't hold, since thete are pairs (3,2) and (3,1). Same first number, different second one. So it is not a function

    imagine that the two numbers of each pair, represent the x and y of some function. So what can not happen is that same x has two or more y asigned to it. Because then the definition is not consistent
