Question

What is the range of the relation (–2, 4), (3, –2), (1, 0), (5, 5)?

A. {–2, 3, 1, 5}
B. {4, –2, 0, 5}
C. {–2, 4, 5, –2}
D. {–2, –1, 0, 5}

Answer 1

list the second numbers of each ordered pair

Answer 2

Domain is all the x values and Range is all the y values.

Answer 3

The only catch, for range you only list a value once. For example.

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

domain: {–3, –2, –1, 0, 1, 2}

range: {5}
