PRACTICE: DOMAIN & RANGE - SET NOTATION

Does the graph represent a function?

• Yes

• No

What is the domain of the relation shown in the table?

• {12}

• {6, 18}

• {3, 9, 15, 16}

• {13}

What is the domain?

• {-2, -1, 0, 1, 8}
• {3, 5, 7 , 9, 0}
• {-2, -1, 0, 1, 3, 5, 7, 8, 9}
• {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

What is the domain of the function?

• {x| x = all real numbers}

• {x| -2 < x < 4}

• {x| -2 ≤ x ≤ 4}

• {x| -6 ≤ x ≤ 3}

What is the Domain?

• All real numbers

• {x|x > 3}

• {x|x = 4}

• {x|x ≥ 3}

What is the range of the table?

• {-4, 0, 1, 3}

• {-2, 0, 2, 3}

• {-4, -2, 0, 1, 2, 3}

• { (0, 0), (2, -4), (3, 3), (-2, 1) }

What is the Range?

• All real numbers

• {y|y ≥ 3}

• {y|y > 3}

• {y|3 ≤ y ≤ 8}

What is the range of the function?

• {x|-7≤x≤6}

• {x|-7<x<6}

• {y|-8<y<2}

• {y|-8≤y≤2}

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{-4, 0, 1, 2}

  R:{-4, -3, 1}

DOMAIN is found by reading the ends of a graph from ___ to ___.

• Right to left

• Left to right

• Bottom to top

• Top to bottom
