Functions Review

What is the range of the function shown?

• {10, 19, 26}
• {-3, 0, 4}
• {-3, 0, 4, 10, 19, 26}
• {0, 16}

What is the domain of the function graphed?

• x < 5
• x ≥ 1
• x > 0
• All real numbers

Which of the inequalities below best describes the domain of the function shown on the graph?

• -2 ≤ x ≤ 2
• -5 ≤ x ≤ -3
• -2 ≤ x ≤ 3
• -5 ≤ x ≤ 3

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

• {12}

• {6, 18}

• {3, 9, 15, 16}

• {13}

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

Is the relation shown in the mapping a function?

• No, because -1 and 4 are pared with 4.

• Yes, because every input is paired with exactly one output.

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: {-4, 0, 1, 2}
  R:{-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}
