If a limit does not exist, explain why. a) lim- *1 x 4 - 1 b) lim Cos(x) X-+0 X c) lim - In(x) x d) lim e' - 1-t 1-0 2) On what intervals is f(x) = x* -4x' both decreasing and concave up? Clearly show your thinking using sign charts for f' and f". Attach a Desmos graph that confirms your answer. 3) Given the function f(x) =x' +15x*+25, a) use derivatives to determine the critical numbers of f, and use the first derivative test to decide whether a local maximum, a local minimum, or neither occurs at each. b) Find the x and y coordinates of the inflection points of f. Attach a Desmos graph, and mark on the graph the critical points and inflection points of f. Page 1 / + 20 utv D O
