Which of the relations given by the following sets of ordered pairs is a function?
A. {(5,4),(4,3),(3,2),(4,5),(2,1)}
B. {(6,1),(-3,1),(3,5),(2,4),(-1,2)}
C. {(1,2),(-4,8),(-3,5),(1,-2),(7,12)}
D. {(5,4),(5,6),(5,8),(5,10),(5,12)}

You can solve this by using the vertical line test. When you do the vertical line test, the vertical line should only pass through one point on the function. That means that there can to be only one value of x for every y. Set B is the only set where the x value doesn't repeat.
