The following table corresponds to first-class postage rates for the U.S. Postal Service. Write a piecewise-defined function in terms of the greatest integer function that models this cost of mailing flat envelopes first class. | Numerade

Postage rates Assume that postage for sending a first-class letter in the United States is 0.44 for the first ounce (up to and including 1 oz) plus 0.17 for each additional ounce (up to and including each additional ounce). a. Graph the function p=f(w) that gives the postage p for sending a letter that weighs w ounces, for 0<w ≤5 b. Evaluate limw →3,3 f(w) c. Interpret the limits limw →1^ f(w) and limw →1^- f(w) d. Does limw →4 f(w) exist? Explain. | Numerade
