3. (7 points) Consider the function f (:13) = 3:3::1[:I +1603. Which of the graphs below best matches the graph of x)? Note that the horizontal scale on the graph goes from :1: = 1000 to a: = 1000, and the vertical scale is unspecied. CLEARLY indicate your ansWer, (a), (b), (c), or (d), and briey EXPLAIN how the TWO most important features of the coefcients and powers appearing in f (:0) justify your conclusion. (a) l y (b) y 1000 x 1 x 1000 00 (c) 1y (d) 3" i l -1 00 1000 x x l - 1000 1000
