Sets and set theory
To solve a business problem, decisions are to be made. Failure or success in solving the problem would be very much dependent on how well the real issue was identified, on the logic used in determining the variables or factors related to the issue, on the analysis utilized for each variable and their interrelationships, on the evaluation of alternatives, and on the final decision arrived at.
According to the so-called decision theory, there are six steps involved (Render et al., 2003) in decision making, namely: 1) clearly define the problem at hand, 2) list the possible alternatives, 3) identify the possible outcomes or states of nature, 4) list the payoff or profit of each combination of alternatives and outcomes, 5) select one of the mathematical decision theory models, and 6) apply the model and make your decision.
The above discussion indicates that the use of a mathematical theory would be of help in evaluating the set of alternatives and possible outcomes that would serve as basis in making a decision that would solve an identified problem.

Applications of functions for the business world
Functions show determinants of a particular variable. As such, a denotation of
D = f (price, income, taste and preference, promotions)
would indicate that demand for a good is a function of its price, the income of the consumer, his taste and preference, and the promotional strategies of the seller or the producer of the good.
Functional relationship would help a decision maker. In the example stated earlier, a producer or a marketer can influence demand by coming up with a reasonable price, or a price that would be appropriate to income and purchasing power of the target buyers, a product that would meet the taste and preference of the buyer, and an effective promotional strategy.
Another online source noted that function is a relation in which each element of the input is associated ...
