function graph math definition Using a Graph to Determine Values of a Function In our last section we discussed how we can use graphs on the Cartesian coordinate plane to represent ordered pairs relations and functions In this section we will dig into the graphs of functions that have been defined using an equation

Definition The graph of a function is the collection of all ordered pairs of the function These are usually represented as points in a Cartesian coordinate system As an example consider the function f 1 2 2 4 3 1 4 3 f 1 2 2 4 3 1 4 3 Graph The word graph has at least two meanings in mathematics In elementary mathematics graph refers to a function graph or graph of a function i e a plot In a mathematician s terminology a graph is a collection of points and lines connecting some possibly empty subset of them

To graph a piecewise defined function we graph each part of the function in its respective domain on the same coordinate system If the formula for a function is different for xa we need to pay special attention to what happens at x a when we graph the function 1 Introduction to Functions definition of a function function notation and examples 2 Functions from Verbal Statements turning word problems into functions Graphs of Functions 3 Rectangular Coordinates the system we use to graph our functions 4 The Graph of a Function examples and an application

Graphing functions is the process of drawing the graph curve of the corresponding function Graphing basic functions like linear quadratic cubic etc is pretty simple graphing functions that are complex like rational logarithmic etc needs some skill and some mathematical concepts to understand Definition Schematic depiction of a function described metaphorically as a machine or black box that for each input yields a corresponding output The red curve is the graph of a function because any vertical line has exactly one crossing point with the curve

We can graph in the coordinate plane when we have 1 input to 1 output If we have a function with 2 inputs to create 1 output we can graph in a 3 dimensional graph of x y z Once you go to even higher inputs we typically would not graph them as we don t what a 4 dimensional space looks like 1 comment A function relates inputs to outputs a function takes elements from a set the domain and relates them to elements in a set the codomain all the outputs the actual values related to are together called the range a function is a special type of relation where every element in the domain is included and
