Such a trend aligns with physical reality; there is a limit on the number of people finite environmental resources can sustain. Another example is a model of a particle in a potential-field. In this model we consider a particle as being a point of mass following a trajectory in space modeled by a function giving its coordinates in space as a function of time. Even many everyday activities carried out without a thought are uses of mathematical models. A geographical map projection of a region of the earth onto a small, plane surface is a model which can be used for many purposes such as planning travel.

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f x or g x instead of y. What is a function in math? In mathematics, a function is a relation between sets that associates to every element of a first set exactly one element of the second set.

The symbol that is used for representing the input is the variable of the function one often says that f is a function of the variable x. How do you solve quadratic equations? To solve a quadratic equation by factoring, Put all terms on one side of the equal sign, leaving zero on the other side. Set each factor equal to zero.
