1.a. Find the domain of f(x)=3+92 + 15x-3, and compute the limit at each of its endpoints. b. Compute '(x), determine the intervals for which is increasing or decreasing, and list (if any) extreme value(s) of f. (Use the following real line). f'(x) = c. Compute "(r), determine the intervals for which the graph of f is concave up or down, and list (if any) inflection point(s). (Use the following real line). "(x)= d. Choose the right graph of f. (Encircle the right letter). a b 15 d 2. Find L(x), the linear approximation to g(x)= at a = 64, and use L to approximate 65+ 65. Fence in blue 3. A homeowner wants to buy fence to enclose a 200 ft rectangular planting bed behind his house so that there is no fence along the wall of the house. The width z of the bed is between 1 and 20 ft from the wall of the house(120) and its length is y. Find the dimensions of the rectangle yielding the minimum perimeter, which you need to find. 15 x Wall
