Identify the domain of the following relation:

• d = x {-6, 14, 2, 28}

• d = x {(-6,14), (0,32), (2,38), (4,44)}

• d = x {-6, 0, 2, 4}

• d = x {14, 32, 38, 44}

What is the range of the following graph?

• all real numbers
• all integers
• any real number greater than zero
• it can not be determined

What is the Range?

• The range is all real numbers greater than or equal to 6

• The range is all real numbers less than or equal to 6

• The range is all real numbers greater than or equal to -10 and less than or equal to 6.

• The range is all real numbers greater than or equal to 6 and less than or equal to -10.

Find the DOMAIN

• {-5, -2, 1, 4}

• {1, -2, 4, -5}

• {-1, 0, 2, 3}

• {0, -1, 2, 3}

Find the Range.

• All Real numbers
• 0 < y < 11
• y ≥ 0
• y > 0

Identify the range in the following relation:
{(9, 7), (6,4), (3,0), (0,-2)}

• {(9, 7), (6,4), (3,0), (0,-2)}
• {9, 6, 3, 0}
• {7, 4, 0, -2}
• There is no range in this relation
