The graph below represents the total number of times a certain website was visited over a five day period.What is the domain and range for the graph? Domain: 0 < x < 150Range:0 < y < 5 Domain:0 ≤ x ≤ 150Range:0 ≤ y ≤ 5 Domain:0 < x < 5Range:0 < y < 150 Domain:0 ≤ x ≤ 5Range:0 ≤ y ≤ 150 3. The graph below shows the path of a golf ball.What is the domain and range of this function? Domain:0 < x < 5Range:0 < y < 100 Domain:0 < x < 100Range:0 < y < 5 Domain:0 ≤ x ≤ 5Range:0 ≤ y ≤ 100 Domain:0 ≤ x ≤ 100Range:0 ≤ y ≤ 5 4. The graph below shows the relationship between the value of a car in dollars and the age of the car in years.What is the range in this situation? x ≥ 0 0 ≤ x ≤ 10.5 y ≤ 21,000 6,000 ≤ y ≤ 21,000 5. A student rode a bike from school to a recreation center. The graph shows the student's distance in miles from the recreation center after riding the bike for x minutes. What is the range of the function for this situation? All real numbers greater than or equal to 0 and less than or equal to 28 All real numbers greater than or equal to 0 and less than or equal to 9 All real numbers greater than or equal to 9 and less than or equal to 28 All real numbers less than or equal to 28 All real numbers less than or equal to 9 6. The senior members of the glee club went on 5 field trips during the school year. The number of vans needed to transport the members of each trip is a function of the number of members who went on each trip. This function consists of only the ordered pairs (12, 1), (28, 2), (35, 3), (42, 3), and (50, 4). What is the range for this situation? 12 ≤ f(x) ≤ 50 {12, 28, 35, 42, 50} 1 ≤ f(x) ≤ 4 {1, 2, 3, 4, 12, 28, 35, 42, 50} {1, 2, 3, 4} 7. Ms. Garcia bought 25 gallons of apple juice for the juice machine at her office. The graph below shows how much juice was left over time.What is the domain of this function? 0 ≤ x ≤ 10 0 ≤ f(x) ≤ 25 0 ≤ x ≤ 25 0 ≤ f(x) ≤ 10 8. An object is thrown from the roof of one building to the roof of another higher building. Its height versus time is plotted below.If the height is a function of time, which best describes the range of this function? All real numbers greater than 0 All real numbers greater than 30 All real numbers greater than or equal to 0 and less than or equal to 5 All real numbers greater than or equal to 30 and less than or equal to 57 9. The graph shows the decay of a radioactive substance over time.What is the domain and range of the graph? Domain: All real numbers greater than or equal to 3Range: All real numbers greater than or equal to 0 Domain: All real numbers less than or equal to 5Range: All real numbers less than or equal to 112 Domain: All real numbers greater than or equal to 3 and less than or equal to 112Range: All real numbers greater than or equal to 0 and less than or equal to 5 Domain: All real numbers greater than or equal to 0 and less than or equal to 5Range: All real numbers greater than or equal to 3 and less than or equal to 112 10.
