For each of the following limits, evaluate or justify that the limit does not exist. If the limit is infinite, justify whether the limit is positive or negative infinity. (a) lim (5+ x cos (-:-)) 2-0 x+11 I-8 + 8 Question 6.2. Let (b) lim kx + 3k x < -1 :{ x + 4k x>-1 Find a value for k such that lim f(x) exists or justify that no such value exists.
