Finding Domain and Range of Linear Function

What is the domain?

• {-2, -1, 0, 1, 8}

• {3, 5, 7 , 9, 0}

• {-2, -1, 0, 1, 3, 5, 7, 8, 9}

• {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

What is the domain of the graph?

Hans opens a new video game store and pays the gaming companies $5.00 for each video game he buys from them. The amount Hans pays is given by f(x)=5x, where x is the number of video games purchased.

Graph the range and domain of the function f(x) = 2x + 3.

• The domain is all integers and the range is all integers.

• The domain is all positive numbers and the range is all positive numbers.

• The domain is all negative numbers and the range is all negative numbers.

• The domain is all real numbers and the range is all real numbers.

Jesse earns $18.50 per hour at his job. He works between 10 and 40 hours per week. The function y = 18.5x for 10 ≤ x ≤ 40 shows the relationship between the hours worked and his weekly pay. What are the domain and range for this function?

• Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 370

• Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 740

• Domain: 10 ≤ x ≤ 50; Range 185 ≤ y ≤ 925

• Domain: 10 ≤ x ≤ 40; Range: 185 ≤ y ≤ 780

Milan has a car that gets 30 miles per gallon. Her car has a 12 gallon tank. The function f(x) = 12(30) - 60x models how long Milan can drive until her tank is empty at 60 miles per hour. What are the domain and range of this situation?

• Domain: 0 < x < 360

  Range: 0 < y < 12

• Domain: 0 < x < 6

  Range: 0 < y < 360

• Domain: all real numbers

  Range: all real numbers

• Domain: 0 < x < 30

  Range: 0 < y < 60

Which is true about the function graphed?

• is a domain value but not a range value.

• is a range value but not a domain value.

• is a range value AND a domain value.
