Mathematics, Functions, and Their Role in our Lives

We perceive several problems related to the functions in many situations in life and develop solutions accordingly. The function shows the effect of one (or more) variable(s) on another variable. In simple terms, one factor can be called the transformation of another factor. When you send a piece of mail by cargo, you pay according to the weight of your cargo. Or imagine using an hourly Internet service in a library or airplane; the more hours you use the Internet, the more you pay.

A group of people wants to rent a bus. The number of people does not affect the cost of rent for a bus. However, the cost per person could change depending on the number of people. The more passengers, the less fee they pay for each passenger. Conversely, if the number of passengers is less, the cost of the bus fee could be more.

The examples are given above help to understand the mathematical function more easily.

Consider shipping by mail. There are actually two situations here; the weight of the cargo sent and the amount of money paid based upon the…
