I know to do 5A, but not 5B and all of 6. Thank you very much for your help.

5. Determine the End Behavior of the following functions: (a) f(x) = ex2-3x (Hint: First look at the End Behavior of x2 - 3x) (b) f(x) = 924-7+23 13x-5x4 6. Compute the following limits (a) lim 2x + sin(x) (b) lim In(x) 7-1 (c) lim 43 (d) lim x + 3 2--3 72 - 9 (e) lim sin (x ) cos(x)
