Domain. Range, Function and Scatterplots

What is the Domain?

• {-3, -1, 1, 3, 5, 7, 9}
• {-3, -2, -1, 0, 1, 2, 3}
• -3 ≤ x ≤ 3
• -3 ≤ x ≤ 9

What is the Range?

• {-3, -1, 1, 3, 5, 7, 9}
• {-3, -2, -1, 0, 1, 2, 3}
• -3 ≤ x ≤ 3
• -3 ≤ x ≤ 9

A graph is presented. What are the domains for this graph?

• -4,-1,4,5,8
• -6,0,2,3,4
• 1,0,9,-4,5
• -6,0,4,5,8

The following ordered pairs represent a relation.
{(1,3) , (5,15) , (2,6), (4,12) , (3,9)}
What are the range values from least to greatest!

• {1, 5, 2, 4, 3}
• {3, 15, 6, 12, 9}
• {3}
• {3, 6, 9, 12, 15}

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}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}

What is domain?

• A set of ordered pairs

• The collection of all inputs or x-values

• The collection of all outputs or y-values

• Has only one output for every input

What is range?

• The collection of all inputs or x-values

• Has only one output for each input

• A set of ordered pairs

• The collection of all outputs or y-values

What is the input?

• 0, 4, 10, 12

• 1, 2, 4, 5, 10, 12

• 0, 4, 10, 4, 12

• 1, 2, 5

What is the output?

• 0, 4, 10, 12

• 1, 2, 4, 5, 10, 12

• 0, 4, 10, 4, 12

• 1, 2, 5

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values
