Question

Does this table represent a function? why or why not x:2,2,3,4,5 y:1,4,4,2,5

Answer 1

No, the table does not represent a function.

Explanation:

By definition, a function will not have 2 or more results for the same input.

The table shows two values of y for the same x: (2,1) and (2,4). The same input, 2, results in two different values, 1 and 4.
