Final answer:

The horizontal axis in a coordinate system is known as the x-axis while the vertical axis is the y-axis. The first value in an ordered pair is the x-value, and the second is the y-value. For the given ordered pairs, the range is {-7, 0, 4, 6}, and the domain is {-2, -1, 0, 3, 5}.

Step-by-step explanation:

In a typical two-dimensional coordinate system, the horizontal axis is called the x-axis, and the vertical axis is referred to as the y-axis. When dealing with an ordered pair, the x-value always comes first, followed by the y-value.

Looking at the given ordered pairs: A(-2,4), B(5,6), C(-1,4), D(0,0), E(3, -7), we can determine the range by listing the distinct y-values of these pairs. This results in the range being {-7, 0, 4, 6}. Similarly, the domain is found by listing the distinct x-values, yielding a domain of {-2, -1, 0, 3, 5}. Therefore, the correct answer to the range is option A, and the answer to the domain is option A as well.
