Application #1: Peaches at the Market


Write a piecewise-defined function to represent the situation described, using the format If(interval,expression) for each piece. Add solid or hollow "points" to the graph to clarify what happens when the function rule changes.


A farm stand at the market has signs up saying "$2 per lb." for peaches, but a man is calling out "Buy at least 5 pounds and it's only $1 per pound!" Let represent the number of pounds of peaches you want to buy and represent the total price.
