Domain and range of a function math is fun. Really clear math lessons pre algebra algebra precalculus cool math games online graphing calculators geometry art fractals polyhedra parents and teachers areas too. You are correct that the curve tends to zero as x tends to infinity but that doesn t tell us the range. Before we start talking about domain and range lets quickly recap what a function is.

The output values are called the range. If x were 11 the relation would still be a function. Access free domain and range of a function interactive worksheets.

Illustrated definition of domain of a function. This post clarifies what each of those terms mean. The domain and range of a function is all the possible values of the independent variable x for which y is defined.

Three common terms come up whenever we talk about functions. The domain is the set of possible x values and the range is the set of possible y values. As a function table and as a set of coordinates.

Domain and range 1 cool math has free online cool math lessons cool math games and fun math activities. For example if both the domain and the codomain are the full set of real numbers and the function f is t t 2 then the range will only be those numbers that are zero or positive. But in fact they are very important in defining a function.

Math is fun that is a function relates an input to an output. An example is the limit of x 1 as x goes to 1 is equal to zero because when looking at the graph when the domain x is equal to 1 the range y is equal to zero. A function relates each element of a set with exactly one element of another set possibly the same set.
