finding the domain of a real-world piecewise function
lucy needs to buy some organic apples, and her grocery store is having a sale on them. if she buys 3 or fewer
pounds of apples, the price will be $1.50 per pound. if she buys more than 3 pounds of apples, the price is $1.10 per
pound. what is the domain of the piecewise-defined function, where x represents the number of pounds of apples?
