In mathematics‚ the exponential function is the function ex‚ where e is the number (approximately 2.718281828) such that the function ex is its own derivative.[1][2] The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change (i.e. percentage increase or decrease) in the dependent variable. The function is often written as exp(x)‚ especially when it is impractical to write the independent variable as a superscript

THE CONSUMPTION FUNCTION To make the income-expenditure model more realistic‚ we will need to introduce other components of demand‚ including the government and the foreign sector. But first we need to recognize that consumers planned expenditures will depend on their level of income. • Consumer Spending and Income The consumption function describes the relationship between desired spending by consumers and the level of income. When consumers have more income‚ they will want to purchase more

of function is rightly considered as one of the most important in all of mathematics. As the point‚ the line‚ and the plane were the basic elements of Euclidean geometry‚ the dominant theory from the time of Ancient Greece until the Modern Age‚ the notions of function and derivative constitute the foundation of mathematical analysis‚ the theory that become central in the development of mathematics since then. Several fields of business mathematics deal directly or indirectly with functions: mathematical
