Identify the input values. Since there is an even root, exclude any real numbers that result in a negative number in the radicand. Set the radicand greater than or equal to zero and solve for x. The solution(s) are the domain of the function.
The domain is the set of all "x" values and the range is set of all "y" values in a set of ordered pairs. Remember that ordered pairs are written as (x, y). When looking at a set of ordered pairs, find the domain by listing all the x values from the relation.
The domain and range of a function y = f(x) is given as domain= {x ,x∈R }, range= {f(x), x∈Domain}. The domain and range of any function can be found algebraically or graphically.

Example 2: The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} .
A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.
The easiest method of finding the range of a function, say y = f(x), is to express x as g(y) and identify the domain set for g(y). This will be the range for the given function f(x).
HOW TO FIND DOMAIN AND RANGE OF A FUNCTION WITHOUT GRAPHINGStep 1 : Put y = f(x)Step 2 : Solve the equation y = f(x) for x in terms of y. ... Step 3 : Find the values of y for which the values of x, obtained from x = g(y) are real and its domain of f.Step 4 :
Overall, the steps for algebraically finding the range of a function are:Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).Find the domain of g(y), and this will be the range of f(x). ... If you can't seem to solve for x, then try graphing the function to find the range.

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

The domain of a function or relation is the set of all possible independent values the relation can take. It is the collection of all possible inputs. The range of a function or relation is the set of all possible dependent values the relation can produce from the domain values.

Find the domain by listing all the x values from the relation. Find the range by listing all the y values from the ordered pairs. Repeated values within the domain or range don't have to be listed more than once. In order for a relation to be a function, each x must correspond with only one y value.
