Chapter 4, Problem 80(choose chapter or problem)
Modeling Data The average typing speed (words per minute) of a typing student after weeks of lessons is shown in the table. A model for the data is (a) Use a graphing utility to plot the data and graph the model. (b) Use the second derivative to determine the concavity of Compare the result with the graph in part (a). (c) What is the sign of the first derivative for By combining this information with the concavity of the model, what inferences can be made about the typing speed as increases?
