Is the following relation a function? Graph of x equals y squared, which results in a horizontal parabola centered on the x axis, going through the origin, and opening to the right. Yes No Question 4 (Yes/No Worth 1 points) (02.01 LC) Is the following relation a function? Two circles are shown, one labeled x and the other labeled y. The x circle contains the numbers 6, negative 2, 4, and negative 1. The y circle contains the numbers 2, negative 2, and 1. Arrows map numbers from x to numbers from y. There are arrows going from 6 to negative 2, from negative 2 to 2, from 4 to 1, and from negative 1 to 1. Yes No Question 5(Multiple Choice Worth 1 points) (02.01 MC) A study was done by an online retail store to determine the rate at which users used its website. A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 36 with an increment of 4. The y axis has a scale of 0 to 60 with increments of 6. A straight line connecting 0, 0 and approximately 36, 54 is drawn. What can be interpreted from the range of this graph? The range represents the 54-month time period of the study. The range represents the 36-month time period of the study. The range represents the number of users each month for 36 months. The range represents the number of users each month for 54 months. Question 6(Multiple Choice Worth 1 points) (02.01 MC) Six-year-old students at an elementary school were given a 20-yard head start in a race. The graph shows how far the average student ran in 30 seconds. A line graph with Distance, in yards, on the x axis and Age of Runner on the y axis. The x axis has a scale from 0 to 80 in increments of 10. The y axis has a scale of 0 to 8 in increments of 2. A straight line connecting 20, 6 and 60, 6 is drawn. Which statement best describes the domain of the function represented in the graph? 6 ≤ x ≤ 60, or x is from 6 to 60 6 ≤ x ≤ 20, or x is from 6 to 20 0 ≤ x ≤ 20, or x is from 0 to 20 20 ≤ x ≤ 60, or x is from 20 to 60 Question 7(Multiple Choice Worth 1 points) (02.01 MC) The finances of a group of pet owners were analyzed to determine how much they were spending on their pet(s) each year. A graph of that data is shown: A graph with Number of Owners on the x axis and Yearly Cost of Pets, in hundreds, on the y axis. The x axis has a scale from 1 to 10 with an increment of 1. The y axis has a scale of 5 to 15 with increments of 1. A curved line connecting 1, 15, approx 3, 7, and 10, 0 is drawn. Would (2.5, 8.5) be a realistic solution for the function? Explain. Yes, it is realistic to have 2.5 owners. No, it is not realistic to have 2.5 owners. Yes, it is realistic that owners spend $850 a year on their pet(s). No, it is not realistic that owners spend $850 a year on their pet(s). Question 8 (Yes/No Worth 1 points) (02.01 LC) Is the following relation a function? {(3, 2), (3, −2), (1, −4), (−1, 2)} Yes No Question 9(Multiple Choice Worth 1 points) (02.01 MC) Dylan created color panels for a wall using a mix of only green and blue paints. He plotted the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph. A line graph titled Color Mix, with Quantity of Blue Paint, in millimeters, on the x axis and Quantity of Green Paint, in millimeters, on the y axis. The x axis has a scale from 0 to 10 with an increment of 1. The y axis has a scale of 0 to 20 in increments of 2. A straight line connecting 1, 2 and 9, 14 is drawn. Which statement best describes the domain of the function represented in the graph? 0 ≤ x ≤ 9 2 ≤ x ≤ 14 1 ≤ x ≤ 9 1 ≤ x ≤ 14 Question 10(Multiple Choice Worth 1 points) (02.01 LC) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y) You must check the box below prior to submitting your exam!
