To determine which set of values represents a function, we need to check if each input in the set is associated with exactly one output. Let's examine each option:

A. (9,5) (10,5) (9, -5) (10, -5)
In this set, both 9 and 10 are associated with multiple outputs (5 and -5). Therefore, this set is not a function.

B. (3,4) (4, -3) (7,4) (3, 8)
In this set, the input 3 is associated with two different outputs (4 and 8). Therefore, this set i...
