Answer 2

Answer: D. No, because one x-value corresponds to the two different y-values.

Explanation:

• A function is a relation from a set of inputs to a set of possible outputs where each input is corresponds to exactly one output.

In the given table , the number 5 corresponds to two different values 2 and 5.

i.e. the one value of x corresponds to two different y-values.

Thus by the definition of function, the given tables does not represent a function.
