Domain Of A Non Function

While dealing with functions we come across various terms such as d o main or r ange that are used during solutions.

Domain of a non function. What is the difference between domain and range of a function. If you ask what do i have to square to get 324 the answer could be 18 or 18. Let r be the relation from a non empty set a to a non empty set b.

Y f x where x is the independent variable and y is the dependent variable. What is the domain and range of a relation. Domain just means the values the relation works on range means the values it produces.

The range of a function is the set of all the outputs a function can give. Then the domain of a function is the set of all possible values of x for which f x is defined. 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.

First we learn what is the domain before learning how to find the domain of a function algebraically what is the domain of a function. Let f x be a real valued function. In simple words domain are the numbers or values of the independent variable that give numerical output values within the function.

For instance the natural domain of square root is the non negative reals when considered as a real number function. The big deal about functions is that they give you a definite i e. All input values that makes the function work to produce any real.
