Domain Of A Function
The domain of each type of function is different.
Domain of a function. The natural domain of a function sometimes shortened as domain is the maximum set of values for which the function is defined typically within the reals but sometimes among the integers or complex numbers as well. If the domain of a function was the interval from 1 to 2 that would mean that all values between 1 and 2 such as 1 1 232 1 664324 3 2 1 1156 2 etc will work in the function. The function f x a x a 0 has the same domain range and asymptotes as f x 1 x. Functions domain and range functions vs.
The domain of a function can also be determined by identifying the input values of a function written as an equation. Enter the function you want to domain into the editor. For instance the natural domain of square root is the non negative reals when considered as a real number function. The domain calculator allows you to take a simple or complex function and find the domain in both interval and set notation instantly.
The domain of a function is the set of all possible inputs for the function. For many functions the domain and range can be determined from a graph. Hence the functions that come from polynomials have as their domain the complete group of real numbers. Now the graph of the function f x a x b c a 0 is a hyperbola symmetric about the point b c.
Relations a relation is just a relationship between sets of information. The pairing of names and heights. For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0.

A function is a well behaved relation that is given a starting point we know exactly where to go. Click the blue arrow to submit and see the result. We can also define special functions whose domains are more limited. Example people and their heights i e.
