Domain and Range

What is the Range?

• y ≥ 6

•  $-\infty<y\le6$  

• -10 ≤ y ≤ 6

• -10 ≤ x ≤ 6

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

Which mapping diagram is not a function?

• 
• 
• 
• 

What is the Range?

• All real numbers

• y ≥ 3

• y > 3

• 3 ≤ y ≤ 8

What is the range of the function?

• $\left\{y:\ -1\le y<+\infty\right\}$

• $\left\{y:\ -1<y<1\right\}$

• $\left\{y:\ 1.5\le y<+\infty\right\}$

• $\left\{y:-1\le y\le1.5\right\}$

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

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

• Function
• Not a Function

What is the range?

• x≥0

• y≥0

• All real numbers

• {0, 1, 2, 3, 4,...}

What is the Domain?

• -3 < x ≤ 3

• -4 ≤ x < 5

• -4 ≤ y ≤ 5

• -3 < y ≤ 3
