First-class postage is $0.39 for a letter weighing up to one ounce and $0.22 for each additional ounce (or fraction thereof). For example, the cost of postage for 1 ounce would be $0.39 and cost for 1.36 ounces would be $0.61. Let C(x) represent the cost of postage for a letter weighing ounces. Use this information to answer the questions below. Write "DNE" if the limit does not exist or the function value is undefined. lim C(r) z 3 = lim C(z) = Z→3+ lim_C(z) = 2-3 C(3) =
