If its exists, give its value. Otherwise, write DNE. f ( x ) = x 2 sin( 1 x ) if x 6 = 0 if x = 0 Problem 2 ( 5pts ) Use lim x sin x x = 1 to find lim x sin 2 (2 x ) x 2 . Problem 3 ( 10pts ) Find a second-degree polynomial f ( x ) = ax 2 + bx + c such that the following conditions are met: f (4) = 9, f (4) = 3 and f 00 (4) = 3. Problem 4 ( 10pts ) If x 2 + xy = 10, find dy dx when x = 2. Problem 5 ( 10pts ) If a ball is thrown vertically upward with a velocity of 4 ft/s, then its height in feet after t seconds is given by s = 4 t- 2 t 2 . What is the maximum height reached by the ball? Problem 6 ( 10pts ) At what point on the given curve y = 9 + 6 e x- 6 x is the tangent line parallel to the line 30 x- y = 4....
