Extracted text: A(x) (8,192) House Figure 1 Figure 2 Tessa has 48 ft of fencing available to construct a fence that will divide her garden into two rectangular sections. Her house forms one side of the garden and a represents the width, as shown in Figure 1. (a) Express the total area of the two sections as a function of x. A(z) = (b) Find the domain of the function. Write your answer as a compound inequality involving x. Domain of A(z): (c) Using the graph of A(x) shown in Figure 2, determine the dimensions that yield the maximum area. Width: ft Length: ft
