Domain and Range Algebra

What is the range of the mapping?

• {1, 2, 4}

• {0, 1, 2, 3}

• [1, 4]

• (1, 4)

• (1, 2, 4)

What is the range of the graph?

• -7 ≤ x < 5

• -3 ≤ x < 1

• -3 ≤ y < 1

• -7 ≤ y < 5

Which is the set of all y-values or the outputs?

• Domain

• Range

• Relation

• Function

Consider the function f whose graph is shown.

The domain of the function is ​ ​ (a)   .

The range of the function is ​ (b)  

• [-1,4]

• [4, -1]

• [-4,1]

• [-4,5]

• [5, -4]

What is the domain and range of this function (in interval notation)?

• Domain: [-8, 8)

  Range: (1.658, 2.342)

• Domain: (-8, 8]

  Range: (1.658, 2.342]

• Domain: (-8, 8]

  Range: [1, 3]

• Domain: [1, 3]

  Range: (-8, 8]

Find the domain and range of the function
Hint:  Use a scratch graph to help you visualize things. 

• Domain: (-∞, ∞)  Range: [-∞, 4]

• Domain: [1, ∞)  Range: (-∞, 4]

• Domain: [-1. ∞) Range: [4, ∞) 

• Domain: [4, ∞) Range: [-1,∞)

What is the range of the function graphed in the image? HINT: range is y values. open circle no equal sign, closed circle gets the equal sign.

• {x | -2 ≤ x < 4}

• {x | -2 < x ≤ 4}

• {y | -3 < y ≤ 3}

• {y | -3 ≤ y < 3}
