Question

NO LINKS OR ASSESSMENT!!!Part 2: 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

#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
