Precalculus with Limits

In Exercises 13-16, graph each function. Compare the graph of each function with the graph of $ y = x^2 $.

(a) $ f(x) = -\frac{1}{2} (x - 2)^2 + 1 $
(b) $ g(x) = \left[\frac{1}{2} (x -1) \right]^2 - 3 $
(c) $ h(x) = -\frac{1}{2} (x +1)^2 - 1 $
(d) $ k(x) = [2(x + 1)]^2 +4 $

Precalculus with Limits

A rancher has 200 feet of fencing to enclose two adjacent rectangular corrals (see figure).

(a) Write the area $ A $ of the corrals as a function of $ x $.
(b) Create a table showing possible values of $ x $ and the corresponding areas of the corral. Use the table to estimate the dimensions that will produce the maximum enclosed area
(c) Use a graphing utility to graph the area function. Use the graph to approximate the dimensions that will produce the maximum enclosed area.
(d) Write the area function in standard form to find analytically the dimensions that will produce the maximum area.
(e) Compare your results from parts (b), (c), and (d).
