Domain and Range from a Graph Interval

What is the domain of the graph?

• y≥1

• x ≥ 1

• All real numbers

• none of these

What is the range of the graph?

• y≥1

• x≥1

• All real numbers

• none of these

What is the domain?

• x = 2

• (−∞ , ∞)

• y = 2

• none of these

What is the domain?

• [-3 , 3)

• [-4 , 5]

• [-4, 5)

• (-3, 3]

Find the domain and the range given the graph of the function.

Find the domain and the range given the graph of the function.

D: ​ (a)  

R: ​ (b)  

What is the domain?

• (-3 , 3)

• [-4, 5]

• (-4, 5)

• (-3, 3]

What is the domain of the function?

• (3, ∞)

• [-3, ∞)

• (-∞, 4]

• (-∞, 4)

What is the domain in Interval notation? Hint: Notice that there are NO ARROWS! The function is a line-segment. It ends on both sides.

• [ -2 , 2 ]

• [ 4 , -4 ]

• -2 ≤ x ≤ 2

• 4 ≥ y ≥ -4

Find the range of the given function.
