Math 1550, Practice Final, Fall 2007 Problem 1. Pick TWO (2) of the following 4 problems. Find the frst derivatives and their critical points. (10 min/20 pts ) (a) f ( x )=2 x 2 e 1 /x (b) f ( x )=(2 x + 1) ln(2 x +1) (c) f ( x ) = sin x ± 2 sin x +3 3 (d) f ( x )= x 2 +4 x - 11 x +5 Problem 2. Pick TWO (2) of the following 4 problems. Evaluate the integrals. [10mts, 20pts] (a) ² e x e e x cos( e e x ) dx (b) ² π/ 4 - π/ 4 cos x sin x sin 2 x +2 dx (c) ² 10 - 10 2+ x (4 x 2 +1) 3 dx (d) ² 6 x (3 x +1) 2 dx Problem 3. Pick ONE (1) of the following two problems. (5 min/20 pts) (a) Discuss the function (even, odd, lim x →±∞ f ( x ), vertical asymptotes, intercepts, increasing, decreasing, maxima and minima, concave up, concave down, points of in±ection, and ²nally a sketch of the graph). Show all work. f ( x )= 1 - 2 x x 10 f ² ( x )= 5 - 9 x 2 x 9 f ²² ( x )= 10(11 - 18 x ) x 12 . (b) Set up integrals (²rst using vertical slices and then with horizontal slices) for the volume of the solid obtained by rotating the region bounded by curves
