Discussion: Piecewise Functions Edit View Insert Format Tools Table Paragraph v 12pt 2 Hey Guys, I just opened a new online store, it's called Mirza's Nut Shop. Where I sell all kinds of nuts. Thc For Shipping the nuts I have a Flat Rate based on the weight in pounds. 0-5 lb $5.00 5-101b $10.00 10-151b $15.00 15-20 lb $20.00 The Rate is stated below in a piecewise function.
