Perform the following steps to find the maximum area of the rectangle shown in the figure

(a) Solve for c in the equation f (c) = f (c + x).(b) Use the result in part (a) to write the area A as a function of x.(c) Use a graphing utility to graph the area function. Use the graph to approximate the dimensions of the rectangle of maximum area. Determine the maximum area.(d) Use a graphing utility to graph the expression for c found in part (a). Use the graph to approximate lim _x0+ c and lim _x∞ c.Use this result to describe the changes in dimensions and position of the rectangle for 0
