Question 1. (6 Points) State the following limits (no need to prove or justify). If the limit is infinite. specify too or -co. If the limit does not exist, and is not infinite, write "DNE." (d) lim _ = - OO sin (x) (b) lim = (e) lim - = 1-40 cos (x + 50 (c) lim - DNE (f ) lim cos (x) x-+0 sin(x) DNE Question 2. (5 Points) Prove f(x) = x4 + x - 3 has a real root in the interval (1, 2). (Recall, f(x) has a real root at a if f(a) = 0.)
