• (10, 10)
• (2, 4)
• (6, 1)
• (-2, 0)

Does this mapping diagram represent a function?

• No, because there are repeating input values
• Yes, because there are no repeating input values

What is the range?

• -4 < x ≤ 5
• -4 ≤ x < 5
• -3 < y < 3
• -3 ≤ y ≤ 5

What is the domain of the graph?

• -7 ≤ x < 5

If I know that f(2) = 4, what is another way I can write my answer?

• 2,4

• (2, 4)

• That is the only way to write it.

What is the definition of a function?

• Has inputs and outputs

• Inputs have different outputs every time

• x-values and

  y-values

• Every input has only one output
