The domain in math is usually defined for relations/functions. What is the Definition of Domain in Math? Inputting the values x =, which is a singleton set. Consider the above box as a function f(x) = 2x. i.e., The domain in math is the set of all possible inputs for the function. 1.ĭomain and Range of Exponential Functionsĭomain and Range of Trigonometric Functionsĭomain and Range of an Absolute Value Functionĭomain and Range of a Square Root FunctionĪ domain of a function refers to 'all the values' that can go into a function without resulting in undefined values.
Let us learn to find the domain and range of a function, and also graph them.
Thus, the range is the possible outputs we can have here, that is, the flavors of soda in the machine. Hence, the domain represents the inputs we can have here, that is, quarters and one-dollar bills. The machine will not give you any flavor of the soda if pennies are input.
Domain and range are the main aspects of functions. Similarly, for functions, we input different numbers and we get new numbers as the result. When you put in a certain amount of money, you can select different types of sodas. Functions in mathematics can be compared to the operations of a vending (soda) machine.
