First-class postage is $0.31 for a letter weighing up to one ounce and $0.28 for each additional ounce (or fraction thereof). For example, the cost of postage for either 1.36 ounces or 1.5 ounces would be $0.59. Let C(x) represent the cost of postage for a letter weighing x 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(x) = %3D lim C(x) = lim C(x) %3D C(3) %3D Find all x-values on the interval (0, 4) where the function is discontinuous. Separate multiple answers with a comma.

Expert Solution
Step 1

Given:

First-class postage is $0.31 for a letter weighing upto one ounce and $0.28for each additional ounceor fraction thereof.

To Find:

Let Cx represent the cost of postage for a letter weighing x ounces, then:a. limx→3-Cxb. limx→3+Cxc. limx→3Cxd. Find all x-values on the interval 0,4 where the function is discontinuous.Separate mutiple answer with a comma.
