This site provides an interactive applet to construct the graph of function when giventhe graph of its derivative. Students can check the accuracy of their graphs and compare it with the result by just clicking on the available options: “check accuracy” and “show results”. This site offers a great help for students of Calculus I who want to practice graphing functions using their derivatives’ graphs. This site can be included as a part of lecture or as an extra online tutorial for students.
The applet is interactive and user friendly. It would be very nice to use in an in-class demonstration or group activity to help students think about how they would construct the graph of a function from the derivative. Exploratory questions are provided to aid students as they investigate.
