Use your graphing calculator to graph each of the following functions and provide the requested information using appropriate interval notation. You will have to set an appropriate window setting to fully see the graphs. To find the x values where the function changes from increasing to decreasing, use the minimum and maximum feature in the Calculate graphing menu of your graphing calculator. You find this by selecting TRACE and number 3: Minimum or 4: Maximum.
