Final answer:
The set of ordered pairs that represents y as a function of x is option 2) (0, 0), (1, 1), (2, 3), (3, 3).
Step-by-step explanation:
The set of ordered pairs that represents y as a function of x is option 2) (0, 0), (1, 1), (2, 3), (3, 3).
In this set, each x-value corresponds to a unique y-value, which is the criteria for a function. However, option 1) has (0, 0) listed twice, which violates the definition of a function. Also, options 3) and 4) have different x-values that correspond to the same y-value, which also violates the definition of a function.
Therefore, option 2) is the correct set of ordered pairs that represents y as a function of x.
