For the given function:a) Describe an appropriate domain and range for the function.b) Make a rough sketch of a graph of the function. c) Briefly discuss the validity of your graph as a model of the true function.(time spent studying, percentage on exam)
What will be an ideal response?
Answers may vary.
a) The domain of the function is the number of hours spent studying for the exam between 0 and 20 and the range is the percentage scored on the exam between 0 and 100%.
b)
c) The function should be roughly increasing. Typically, the more hours spent studying, the higher the percentage. However, there are many students who barely study and still perform well along with students who study often and still perform poorly.
