Graphical Reasoning Consider the function f ( x ) = cos 2 π x x 2 + 1 , 0 < x < 4 (a) Use a computer algebra system to graph the function and use the graph to approximate the critical numbers visually. (b) Use a computer algebra system to find f' and approximate the critical numbers. Are the results the same as the visual approximation in part (a)? Explain.
