Answer 2

A.) {-2, 2, 5, 7}

Explanation:

The range of a set of ordered pairs is the set of second numbers in the pairs.

Here, the second numbers are 2, 5, 7, -2. When written as a set, it is convenient (though not required) that they be written in numerical order:

{-2, 2, 5, 7} . . . . matches choice A
