Module 3 Review

Choose the relationship that fits the table, graph, and mapping diagram.

• {(-1,0), (0,1), (2,1), (3,4)}
• {(-2,-1), (-1,1), (2,3), (3,4)}
• {(-4,5), (-2,3), (0,1), (2,-1)}
• {(-2,-1), (-1,0), (0,-1), (2,-1)}

Give the domain and range of the relation.
{(-2,-1), (-1,0), (0,-1), (1,0), (2,-1)}

• D: {-2, -1, 0, 1, 2}
  R: {-1, 0}
• D: {-1, 0}
  R: {-2, -1, 0, 1, 2}
• D: {-2, -1, 0, 1, 2}
  R: {-1, -1, -1, 0, 0}
• D: {-2 < x < 2}
  R: {-1 < y < 0}

Give the domain and range. Tell if it is a function.

• D: {-4, -2, 0, 2}
  R: {-2, -2, 1, 1}
  Function
• D: {-4, -2, 0, 2}
  R: {-2, 1}
  Function
• D: {-4, -2, 0, 2}
  R: {-2, -2, 1, 1}
  Not a Function
• D: {-4, -2, 0, 2}
  R: {-2, 1}

• The cat has 2 eyes
• The cat has 2 kittens
• The cat has 4 paws
• The cat weights 5.4 kg

Which one of the following is discrete data?

• Sam is 160 cm tall
• Sam weighs 60 kg
• Sam ran 100 meters in 10.2 seconds
• Sam has two brothers and one sister

• -4 ≤ x ≤ 3
• -1 ≤ x ≤ 4
• 4 < x < 3
• -1 < x < 4

Evaluate the function for the given inputs.
For f(x) = -2x + 4,
find f(x) when x = -5

• f(-5) = -6
• f(-5) = -3
• f(-5) = 14
• f(-5) = 2

Is the relation a function?{(1,5),(1,7),(3,9),(4,11)}

• Yes
• No
