A graph of a relation is shown below:
Which statement about the relation is true? 

• The relation is not a function of x because all functions are linear
• The relation is a function of x because values of x increase towards infinity
• The relation is a function of x because each value of y corresponds to one value of x
• The relation is not a function of x because more than one value of y may correspond to the same value of x
