It cover topics such as graphing parent functions with transformations, limits, continuity, derivatives, and integration. While the study of sets and functions is important in all computational mathematics courses, it is the study of limits that distinguishes the study of calculus from the study of precalculus. Functions and their graphs input x output y if a quantity y always depends on another quantity x in such a way that every value of x corresponds to one and only one value of y, then we say that y is a function of x, written y f x.
