Unformatted text preview: Partial solutions to the Math 151 review problems for Exam 2 These are not complete solutions. They are only intended as a way to check your work. (1) The limit is 4. The LH opital Rule is much more efficient than using long division to factor ( x 1) 2 out of the numerator and denominator. (2) The LH opital Rule gives 1 / 3. In Math 152 you will learn a more efficient way to find this limit. (3) The horizontal asymptotes are y = 1 7 and y = 1 7 . (4) All of your answers except horizontal asymptotes can be checked using your graphing calculator and a viewing window with 4 x 4 and 4 y 4. The horizontal asymptote for (a) is y = 1. The horizontal asymptote for (b) is y = 0. (5) The critical points are x = 1 and x = 2 / 5. The inflection points are x = 0 and x = 3 / 10. If you use your graphing calculator to check the remaining answers, then you will have to choose the graphing window carefully to see confirmation of the following: The function is decreasing on ( 1 , 2 / 5) and (2 / 5 , 1). This is not obvious if the viewing window is 2 x...
