Functions Review

Why is the following relation NOT a function?

• There are points on the graph with the same x-coordinate but different y-coordinates.

• The graphed relation is not a line.

• There are infinitely many points on the graph.

• The domain of the graph does not include all real numbers.

A relation contains the ordered pairs (3,1) , (9,7), (10,4) and (x,y). What are the values of x and y so the relation is a function?

• x = 17 and y = 1

• x = 3 and y = 5

• x = 9 and y = 12

• x = 10 and y = -2
