Answer:
piecewise function
Explanation:
A factory manufactures widgets based on customer orders.
If a customer's order is for less than w widgets, the customer's cost per widget is d dollars. customer order < w widgets
If a customer's order is for at least w widgets, the customer's cost per widget is decreased by c cents for each widget ordered over w widgets.
customer order > w widgets
So here we have two different conditions . we can represent two or more functions using piecewise functions
Hence piecewise function would be the best model.
