Unformatted text preview: ecial Functions The floor function is the function x = n ∈ Z where n ≤ x < n + 1. The ceiling function is the function x = n ∈ Z where n − 1 < x ≤ n. y y 2 1 2 1 -2 -1 12 -1 -2 The Floor Function x -2 -1 12 -1 -2 x The Ceiling Function Outline Piecewise-Defined Functions Graphing Piecewise-Defined Functions Applications Application Example As of May 2007, the first rate postage rate for large envelopes sent through U.S. mail was $0.80 for the first ounce, then an additional $0.17 per ounce thereafter, up to 13 ounces. Give the formula for the postage rate as a function of weight. State the domain and range. P (w ) = 80 + 17 w − 1 for 0 < w ≤ 13....
