Key Features of Functions and Graphs form b

The domain is the set of all the:

• graphs

• x-values

• y-values

• z-values

The Range is the set of all:

• y- values

• x-values

• x and y values

• graphs in the domain

Match the domain and range with the correct graph

• D: {x| -4 ≤ x ≤ 2}

  R: {y| -2 ≤ y ≤ 4}

• 
• D: {x| x = ARN}

  R: {y| y ≥ 0}

• 
• D: {x| x ≤ 5}

  R: {y| y ≤ 2}

• 
• D: {x| x = ARN}

  R: {y| y ≤ 1}

•
