What is the domain and range of each function

1. x (3, 5, 7, 8, 11)
y ( 6, 7, 7, 9, 14)

2. x (-3, -1, 2, 5, 7)
y (9, 5, 4, -5, -7)

Answer 1

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

Explanation:

The domain is the set of all x values in the function. The range is the set of all y values in the function. It is written in parenthesis from least to greatest. Do not repeat values even if the function has them more than once.

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)
