How do I find the domain and range of a function?
How to Find The Domain and Range of an Equation? To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain. To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
How do you find the domain and range of a problem situation?
To determine the domain of a given situation, identify all possible x-values, or values of the independent variable. To determine the range of a given situation, identify all possible y-values, or values of the dependent variable.
What is range and domain of a function example?
Example: a simple function like f(x) = x2 can have the domain (what goes in) of just the counting numbers {1,2,3,...}, and the range will then be the set {1,4,9,...} And another function g(x) = x2 can have the domain of integers {...,-3,-2,-1,0,1,2,3,...}, in which case the range is the set {0,1,4,9,...}
How do you find the domain and range of a function in class 11?
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).
