In mathematics , the graph of a function f is, formally, the set of all ordered pairs x , f x , such that x is in the domain of the function f. In the common case where x and f x are real numbers , these pairs are Cartesian coordinates of points in the Euclidean plane and thus form a subset of this plane, which is a curve in the case of a continuous function. This graphical representation of the function is also called the graph of the function. In the case of functions of two variables, that is functions whose domain consists of pairs x , y , the graph can be identified with the set of all ordered triples x , y , f x , y. For a continuous real-valued function of two real variables, the graph is a surface. The concept of the graph of a function is generalized to the graph of a relation.

A jetliner changes altitude as its distance from the starting point of a flight increases. The weight of a growing child increases with time. In each case, one quantity depends on another. There is a relationship between the two quantities that we can describe, analyze, and use to make predictions. In this section, we will analyze such relationships. A relation is a set of ordered pairs. Consider the following set of ordered pairs.

Defining the Graph of a Function The graph of a function f is the set of all points in the plane of the form x, f x. So, the graph of a function if a special case of the graph of an equation. Recall that when we introduced graphs of equations we noted that if we can solve the equation for y, then it is easy to find points that are on the graph. We simply choose a number for x, then compute the corresponding value of y. Graphs of functions are graphs of equations that have been solved for y! It is easy to generate points on the graph.

Graphing Types of Functions. Learning Objective s., In mathematics , a function [note 1] is a relation between sets that associates to every element of a first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

We begin by reviewing the basic properties of linear and quadratic functions, and then generalize to include higher-degree polynomials.

Recall that slope can be thought of as.
