Part 2: Domain and Range of Graphs

Domain is the set of input valuesRange is the set of output valueFunction is passes the vertical line test#2

Domain:

- 2 ≤ x < 2 or x∈ [-2, 2)

Range:

-4 ≤ y < 0 or y ∈ (-4, 0]

Function:

YES - passes the vertical line test#4

Domain:

- 0 ≤ x < 4 or x∈ [0, 4)

Range:

-2 < y < 2 or y ∈ (2, 2)

Function:

N0- doesn't pass the vertical line test#6

Domain:

- 4 < x < 4 or x∈ (-4, 4)

Range:

-4 < y ≤ -2 or y ∈ (-4, -2]

Function:

YES - passes the vertical line test
