Sample exam iii math 135, spring 2008. 1 e (a) limx (b) limx 0 (c) limx 1 (cid:16) 1 (d) limx 0 (e) limx 2 x 1 . 5+2x 3 x x 2 : find the local and absolute extreme values of the function given in the interval (a) f (x) = x4. Are there any in ection points: sketch the graph of the function f (x) = Determine: (1) the domain, (2) symmetries (if any), (3) the critical points, (4) intervals where the function increases or decreases, (5) concavity and in ection points, and (6) limits at in nity. Remember, a sign chart is always of great help: sketch the graph of the function f (x) = x4. 2x2, indicating the same steps as above.
