3.1 Homework Quiz 10/17

Choose the best answer describing the relation in the map.

• It is a function because there is exactly one output (y) for every input (x)

• It is a function because there are more outputs (y) then inputs (x)

• It is NOT a function because there or two outputs (y) that have the same input (x)

•  It is NOT a function because there are two inputs (x) that have the same output (y)

Does the graph represent a function, and why?

• It does represent a function because it passes the vertical line test

•  It does represent a function because there are no lines connecting the dots

• It does NOT represent a function because it does NOT pass the vertical line test

• It does NOT represent a function because there are no lines connecting the dots

Find the domain and range of the function represented in the graph

• Domain {-2, 0, 2}     

   Range  {-2, -1, 0, 1, 2}

• Domain  {-2, -1, 0, 1, 2}

  Range  {-2, 0, 2}  

• Domain:  {-2 ≤ x ≤ 2}

  Range:  {-2 ≤ y ≤ 2}

Find the domain and range of the function represented in the graph

• Domain:  {-4 ≤ x ≤ 2}

  Range:  {2 ≤ y ≤ 6}

• Domain:  {2 ≤ x ≤ 6}

  Range:  {-4 ≤ y ≤ 2}

• Domain {-4, -3, -2, -1, 0, 1, 2}     

   Range  {2, 3, 4, 5, 6}

• Domain {2, 3, 4, 5, 6}     

   Range  {-4, -3, -2, -1, 0, 1, 2}

The function y = 25x + 500 represents your monthly rent (y) in $ when you pay (x) days late

Identify the Independent and Dependent Variables

• Independent Variable (x) = # of days late

  Dependent Variable (y) = Monthly rent amount

• Independent Variable (x) = Monthly rent amount

  Dependent Variable (y) = # of days late
