answer the following

Do the following for the function given below. (speed, stopping distance of a car) a. Describe an appropriate domain and range for the function. h. Make a rough sketch of a graph of the function. 0. Briey discuss the validity of the graph as a model of the true function. a. Choose the appropriate domain forthe function below. O A. The domain is realistic car speeds: 10 feet per second to 70 feet per hour. 0 B. The domain is stopping distances for each of the given speeds: 10 feet to 350 feet. C. The domain is realistic car speeds; 10 miles per hour to 70 miles per hour. 0 D. The domain is stopping distances for each of the given speeds; 10 miles to 350 miles. Choose the appropriate range for the function below. O A. The range is stopping distances for each of the given speeds; 10 feet to 350 feet. 0 B. The range is stopping distances for each of the given speeds; 10 miles to 350 miles. 0 C. The range is realistic car speeds; 10 feet per second to 70 feet per hour. 0 D. The range is realistic car speeds; 10 miles per hour to 70 miles per hour. b. Make a rough sketch of a graph of the function. Choose the correct graph below. Let v represent speed in miles per hour and d represent stopping distance in feet. O C.

Briey discuss the validity of the graph as a model of the tme function. Choose the correct answer below. 0 A. The graph is not a valid model of the true function. 0 B. The graph is a valid model of the function because it is reasonable to assume that stopping distance in feet increases as speed in miles per hour increases
