{(-1,-3),(3,2),(3,7)} NO WAY, two y values for x = 3 ???
{(-3,7),(3,-7),(3,7)} SAME PROBLEM!
{(-1,4),(-1,7),(3,5)} BORING at x = -1y can not be both 4 and 7
the last one works. Y can be the same at 2 places in x
but can not be different at a particular x
Which of the following relations represent a function?
{(-1,-3),(3,2),(3,7)}
{(-3,7),(3,-7),(3,7)}
{(-1,4),(-1,7),(3,5)}
{(-1,4),(2,7),(3,7)}
