Linear and piecewise functions are very helpful in the business field. Not only it will help us get a track of our revenue and loss but it will also help us budget our money. From budgeting to making predictions, if we use linear functions, we are able to find the cost, profit, revenue, loss and breakeven points. On the other hand, piecewise function helps us to present data of a problem with various conditions like know if the cost per piece of a certain item is discounted once the number ordered exceeds a certain value.

The projects here have used both linear and piecewise functions where solving problems involving the cost of an item, the revenue and the profit gained by a business are shown.

Rational Functions can be useful for representing real life situations and for solving problems like distance, speed, time travelled and working hours of a person or people working together.

These projects show a variety of problems involving the planned route of people like the time travelled, speed and distance to get from one place to another as well as the hours of work done by one person or many.

Inverse function is very important when solving problems with reverse concepts. Like in money, because it helps you convert one currency to another.

These outputs that are shown here provide ideas on how to apply inverse functions in the real world involving concepts like area, cost of something, currency and temperature conversion, etc.
