The correct answer is:

A) p (x) and q (x) have the same domain and the same range.

Explanation:

The domain is the set of numbers we can use for x. There are no restrictions on this domain; that is, there is no number that will not give us a real answer for x.

The range is the set of numbers for y. There is no number that we cannot get as a value for either function for y.

This means that both the domain and the range is the set of all real numbers.
