The Postage function. The cost of sending a large envelope via U.S. first-class mail in 2014 was $0.98 for the first ounce and $0.21 for each additional ounce (or fraction thereof). (Source; www.usps.com .) If x represents the weight of a large envelope, in ounces, then p ( x ) is the cost of mailing it, where p ( x ) = $ 0.98 , if 0 < x ≤ 1 , p ( x ) = $ 1.19 , if 1 < x ≤ 2 , p ( x ) = $ 1.40 , if 2 < x ≤ 3 , And so on, up through 13 ounce. The graph of p is show below. Using the graph of the postage function, find each of the following limit, if it exists. lim x → 3 p ( x )
