Chapter 3 Review: Sections 1-3

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Describe the graph .

• A non-linear function that passes the vertical line test.

• A non-function because a vertical line will touch two points in some places.

• A linear function which passes the vertical line test.

• A non-function because it is not a straight line.

• Not linear and a function.

• Non linear and not a function.

• Linear and a function

• Linear and not a function.

• Function, because the inputs do not repeat

• Not a Function, because the inputs repeat

• Function, because the outputs do not repeat

• Not a Function, because the inputs do not repeat

• Function, because the inputs repeat

• Not a Function, because the inputs repeat

• Function, because the outputs do not repeat

• Not a function, because the outputs do not repeat

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}

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

• No, because the graph is made up of individual points and not a line.

• Yes, because the graph is made up of individual points and not a line.

Identify the range of the following relation:

• {-6, 14, 2, 28}
• {-6,14, 0, 32, 2, 38, 4,44}
• {-6, 0, 2, 4}
• {14, 32, 38, 44}

Is this relation a function?

• Function because no x-values repeat.

• Not a Function because a domain value repeats.

• Function because no y-values repeat.

• Not a function because a range value repeats.
