Domain Of A Function Calculator Interval Notation

What is interval notation.

Domain of a function calculator interval notation. Interval notation combines inequality or set notation with its graph and allows us to accurately express an interval with easy to understand symbols. Recall that the domain of a function is the set of possible input values x values of the function. In advanced mathematics interval notation is the preferred method of representing domain and range and is cleaner and easier to use and interpret.

Domain f x x 3. Informally if a function is defined on some set then we call that set the domain. Really clear math lessons pre algebra algebra precalculus cool math games online graphing calculators geometry art fractals polyhedra parents and teachers areas too.

For example take f x dfrac x 2 x 3. Why should we care. For example the function takes the reals domain to the non negative reals range.

Domain of f x frac sqrt x 1 x 2 4 in interval notation is 1 2 cup 2 infty. Finding the domain of a function cool math has free online cool math lessons cool math games and fun math activities. Domain of a function calculator.

In interval notation that is written infty 3 cup 3 infty. Learn how to find the domain of rational functions. Both of these functions.

It is much easier in general to look at the equation of a function and figure out its domain than it is to figure out its range. Enter the function you want to domain into the editor. Domain f x cos 2x 5 domain f left x right sin left 3x right.
