Domain & Range

What is the range?

• {-2,2,5}
• {1,3,5,6}
• all real numbers 
• -2<y<5

What is the range of the function shown?

• {10, 19, 26}
• {-3, 0, 4}
• {-3, 0, 4, 10, 19, 26}
• {0, 16}

What is the DOMAIN of this graph?

• x < -3

• x ≤ -3

• x > -3

• x ≥ -3

What is the DOMAIN of this function?

• -∞ ≤ x ≤ ∞

• -∞ ≤ x ≤ ∞

• ∞ < x < ∞

• -∞ < x < ∞

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

All of the y values or outputs are called what?

• Domain
• Range

All of the x values or inputs are called what?

• Domain
• Range

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)
Range is the y values 
(x,y)

• -4, 4, 8, 9
• -2, 3, 8, 10
• (9, -2) ( 4, 3)
• (8, 10) (-4, 8)

Identify the domain of the following relation:
Remember domain is the "x" values

• -6, 14, 2, 28
• (-6,14), (0,32), (2,38), (4,44)
• -6, 0, 2, 4
• 14, 32, 38, 44

IS THIS GRAPH DISCRETE AND CONTINUOUS?  

• DISCRETE
• CONTINUOUS
