They differ by just one number, but only one is a function. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. Great app Just punch in your equation and it calculates the answer. If each number in the domain is a person and each number in the range is a different person, then a function is when all of the people in the domain have 1 and only 1 boyfriend/girlfriend in the range.Ĭompare the two relations on the below. Use our algebra calculator at home with the MathPapa website, or on the go with MathPapa mobile app. Home > Algebra calculators > Domain of a function calculator. Some people find it helpful to think of the domain and range as people in romantic relationships. To get the function’s range, just write x g (y) and then discover the domain of g (y). To determine the values of the independent variable x, we simply solve the equation to determine the domain of the function. Gino below, has more than 1 student in a classroom.Ī way to try to understand this concept is to think of how mothers and their daughters could be represented as a function.Įach element in the domain, each daughter, can only have 1 mother (element in the range). Let’s use algebra to determine the domain and range of this function. If we put teachers into the domain and students into the range, we do not have a function because the same teacher, like Mr. Therefore, relation #2 does not satisfy the definition of a mathematical function. On the other hand, relation #2 has TWO distinct y values 'a' and 'c' for the same x value of '5'. Since relation #1 has ONLY ONE y value for each x value, this relation is a function. In mathematics, what distinguishes a function from a relation is that each x value in a function has one and only ONE y-value.

Like a relation, a function has a domain and range made up of the x and y values of ordered pairs. The Domain and Range Calculator finds all possible x and y values for a given function. A function is a set of ordered pairs such as. Calculus Domain and Range Calculator Step 1: Enter the formula for which you want to calculate the domain and range.As a quick refresher, recall that the domain is the set of all possible x-values which will make the function 'work', and will output real y-values.

Functions are a special kind of relation.Īt first glance, a function looks like a relation. This calculator lets you explore the domain and range examples discussed on the previous page, Domain and Range of a Function.
