Question 1. (6 Points) State the following limits (no need to prove or justify). If the limit is infinite, specify +oo or -co. If the limit does not exist, and is not infinite, write "DNE." (a) lim (d) lim 1 3-10 22 - = x -0- X (b) lim sin (x) 1+40 cos (x) = (e) lim = + (c) lim - = DNE (f) lim cos (x) x-+0 sin(x) DNE Question 2. (5 Points) Prove f(a) = 24 + 2 - 3 has a real root in the interval (1, 2). (Recall, f(x) has a real root at a if f(a) = 0.)
