FIND DOMAIN AND RANGE FROM GRAPH WORKSHEET

Answer Key

1)  

Not a function

Domain = {-3, -2, 1, 4}

Range = {-4, -2, 0, 3, 5}

2) 

Not a function

Domain = -3 ≤ x ≤ 3

Range = -4 ≤ y ≤ 3

3)  

It is a function

Domain = -4 < x < ∞

Range = 1 ≤ y < ∞

4) 

Not a function

Domain = -2 ≤ x ≤ 2

Range = 0 ≤ y ≤ 4

5)  

It is a function

Domain = All real numbers

Range = All real numbers

6)

It is a function

Domain = All real numbers

Range = -5 ≤ y ≤ ∞

7)

Not a function

Domain = 0 ≤ x ≤ ∞

Range = -∞ ≤ y ≤ ∞

8) 

Not a function

Domain = All real values

Range = {1, 3}
