Detailed explanation-1: -Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Detailed explanation-2: -How to Find the Range of a Function. Consider a function y = f(x). The spread of all the y values from minimum to maximum is the range of the function. In the given expression of y, substitute all the values of x to check whether it is positive, negative or equal to other values.
Detailed explanation-3: -Ans : The range of a set of numbers is the difference between its highest and lowest values. To find it, subtract the lowest number from the highest in the distribution. Ans : Domain of the function f(x)=|x-1| is R, Whereas range=[0, ∞].
Detailed explanation-4: -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.
