| 38. GENERAL: Windchill Enter the formula for windchill from the Graphing Calculator Exploration on page 434 and again replace y (temperature) by 32 so that it becomes a function of one variable, x (wind speed). a. Graph the function on the window [0, 45] by [0, 40]. b. Use NDERIV or dy/dx to find the slope of this curve at x = 5. Interpret the answer. c. Repeat part (b) but for x = 20, interpreting the answer. d. What do the answers indicate about the windchill effect of additional wind on a calm day as opposed to on an already windy day? a T
