Test 3 Spring 2011 MATH 1550 - 19 p. 1 Name: Show several steps for each calculation problem. Partial credit will be given. Read the directions for each problem and solve the problem using the stated method. Check your work if you have time. Good luck. 1. Draw a graph that corresponds to the following data. Make sure to appropriately label your graph. Interval (- , - 1) (-1,1) (1, 4) (4, ) Asymptotes f + - - - Horizontal y = -2 f ′′ + + - + Vertical x = -1 2. Write out, in summation notation, the Riemann sum R 6 for the function f ( x ) = e 3 x 2 on the interval [2 , 4].
