Unformatted text preview: Let f x ( )= 4 x 3-12 x 2 a) Identify where the extrema of f occur. b) Find the intervals on which f is increasing the intervals on which f is decreasing. c) Find where the graph of f is concave up and where it is concave down. d) Sketch a possible graph for f . (Just show shape not location of points) Calculus Section 4.3 Page15 Example 4 Using the Graph of f Use the graph of the function f to estimate where a) f and b) f are 0, positive, and negative. Example 5 Using the Graph of f Use the graph of f to draw the corresponding thumbnail. Then estimate the intervals on which the function f is a) increasing or b) decreasing. c) Estimate where f has local extreme values Assignment III-3b Pages 203 205 #1 6 all*, 33, 34, 37, 39, 41, 43, 45, 47, 48, Graphing Session II Sheet 2 2 y = f x ( ) 2 2 y = f x ( ) y = f x ( ) y = f x ( )...
