function of a graph example In this section we will dig into the graphs of functions that have been defined using an equation Our first task is to work backwards from what we did at the
A graph is just another way of representing a function a relation that pairs each element in its domain with exactly one element in its range So what is the proper instruction Determine whether the points on this graph represent a function Now just as a refresher a function is really just an association between members of a set that we call the domain

The graph of a function is the graph of all its ordered pairs x y x y or using function notation x f x x f x where y f x y f x f name of function x x A function is like a machine that takes an input and gives an output Let s explore how we can graph analyze and create different types of functions
Use the vertical line test to determine if the graph is a function If you can draw a vertical line anywhere in the coordinate plane and the line only crosses the graph once then the The graph of a function is the set of all points whose co ordinates x y satisfy the function displaystyle y f left x right y f x This means that for each x value there is

To graph a function I begin by determining the domain and range which are the set of all possible inputs x values and outputs y values respectively With this In mathematics the graph of a function is the set of ordered pairs where In the common case where and are real numbers these pairs are Cartesian coordinates of points in a
The basic idea of graphing functions is Identifying the shape if possible For example if it is a linear function of the form f x ax b then its graph would be a line if it is a 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 We could also define the graph of f to be the graph of the
