![]() The Codomain is actually part of the definition of the function.Īnd The Range is the set of values that actually do come out. The Codomain is the set of values that could possibly come out. The Codomain and Range are both on the output side, but are subtly different. Or if we are studying whole numbers, the domain is assumed to be whole numbers.īut in more advanced work we need to be more careful! Codomain vs Range.Whether youre studying calculus, algebra. The calculator will also plot the function's graph. ![]() It can find the following for a function: parity, domain, range, intercepts, critical points, intervals of increase/decrease, local and global extrema, concavity intervals, inflection points, derivative, integral, asymptotes, and limit. ![]() Usually it is assumed to be something like "all numbers that will work". Step 1: Enter the Function you want to domain into the editor. The Domain and Range Calculator is a tool designed to help you determine the domain and range of a function. The Function Calculator is a tool used to analyze functions.Yes, but in simpler mathematics we never notice this, because the domain is assumed: So, the domain is an essential part of the function. In this case the range of g(x) also includes 0.Īlso they will have different properties.įor example f(x) always gives a unique answer, but g(x) can give the same answer with two different inputs (such as g(-2)=4, and also g(2)=4) Example: a simple function like f(x) = x 2 can have the domain (what goes in) of just the counting numbers Įven though both functions take the input and square it, they have a different set of inputs, and so give a different set of outputs.
