Answer:

2) II and IV

Step-by-step explanation:

A function will have only one output value for any given input.

II. The first values of the ordered pairs are all unique. This is a function.

III. The graph shows two different output values for each x input that is greater than 0.

IV. A polynomial always represents a function.
