Fall 2017: (19 pts) using the function f (x) plotted in the gure, nd the following values, or write dne if they (cid:58) do not exist. Solution: (a) lim x 2 f (x) = dne (d) f (1) = dne (b) lim x 2 f (x) = 2 (e) lim x 2 f (x) = 3 (c) lim f (x) = 0 (f) f ( 3 x 2+ 5 ) = 4 (g) the average rate of change of f on(cid:2) 2, 1. 2(cid:3) is (h) the values of x in ( 3, 3) where f is not differen- 2 tiable are 2, 0, 1, 2 : (10 pts) use the graph of f (x) shown above to sketch a graph of the derivative f (x). Solution: here are two possible solutions. (cid:58: (17 pts) the following problems are not related. powered by (a) if tan = 1/x, < < 3 .
