Use your calculator to obtain a graph of the area function. Choose a window that shows both horizontal intercepts and the vertex. Locate the point on your graph that represents your answer to Question 2 by letting Y2 = the corresponding area, then finding the intersection. (Note there will be two intersections, you must choose the correct one). Draw an arrow pointing to the point that represents your answer to Question 2, and write the coordinates as an ordered pair.

Sorry I guess I should have posted this as well. A construction company wishes to build a rectangular enclosure to store machinery and equipment. The site selected borders on a river that will be used as one of the sides of the rectangle. Fencing will be needed to form the other three sides. The company has 528 feet of 10- foot high chain-link fencing. The questions that follow should help you determine the dimensions of the rectangle that will produce the maximum area for the storage site. Assume that the company wishes to use all of the fencing, and that “width” refers to the measure of each of the two sides that are perpendicular to the river, and “length” refers to the measure of the side parallel to the river (see diagram). For the questions that follow, all measurement answers are to be given with the correct unit label, e.g. feet, square feet, etc.
