Domain & Range: More Practice!

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT 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

What variable typically represents the domain?

• x

• y

What variable typically represents the range?

• x

• y

Is this graph a function or not a function? 

• Function 
• Not a Function

Is this set of ordered pairs a function or not a function? 

• Function
• Not a Function 

Is this mapping a function or not a function? 

• Function
• Not a Function

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?

• {-3, -1, 2, 4}
• {0, 4, 7} 
• {0, 4, 4, 7}
• {7, 4, 0}

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 domain and range for the function:

{(-5,2), (8,-4), (-7, 2), (5,0)}

• Domain: {-4,0,2}

  Range: {-7, -5, 5, 8}

• Domain: {-7, -5, 5,8}

  Range: {-4, 0, 2}
