Unformatted text preview: intervals of increase and decrease . Remember this means nding the derivative and then using this to nd critical points, where the sign of the derivative might change. F. Find local maxima and minima using either the First Derivative Test or the Second Derivative Test. G. Using the second derivative and the Concavity Test, nd the intervals of upward and downward concavity . Where are the inection points, if any? H. Finally, put it all together to get a sketch of the graph! Examples. Try out your newfound wisdom by sketching graphs of the following functions: f ( x ) = xe x , h ( t ) = 1 1+ e-t , and m ( ) = cos 2 ( )-2 sin( ). f ( x ) = e-( x-4) 2 . Homework. Do exercises 12, 29, 32, and 47 from Section 4.5 (pages 314-315) of your text. This is due on Friday, November 16th ....
