Part 1: Domain and Range of Graphs
​

Answer 1

• Domain is the set of input values
• Range is the set of output value
• Function is passes the vertical line test

#1

Domain:

• - 5 < x < 5 or x ∈ (-5, 5)

Range:

• -5 < y < 5 or y ∈ (-5, 5)

Function:

• YES - passes the vertical line test

#3

Domain:

• - 5 < x ≤ 5 or x∈ (-5, 5]

Range:

• -3 < y ≤ 2 or y ∈ (-3, 2]

Function:

• YES - passes the vertical line test

#5

Domain:

• - 5 < x < 3 or x∈ (-5, 3)

Range:

• 0 < y < 4 or y ∈ (0, 4)

Function:

• N0- doesn't pass the vertical line test
