Free Interval Notation Calculator - convert inequalities into interval notations step by step

Find the domain of any function with Mathos AI’s Domain Calculator. Get step-by-step solutions to understand function domains and their restrictions.

For the function f(x) = 1/x, the domain would be all real numbers except for x = 0 (x<0 or x>0), as division by zero is undefined. ... A function basically relates an input to an output, there’s an input, a relationship and an output. For every input... ... scientific calculator inverse calculator simplify calculator distance calculator fractions calculator interval notation ...

Determine the Domain: The domain is the set of all valid input values (x-values) for the function. For example: If the function is polynomial (like f(x)=x2), the domain is all real numbers, expressed in interval notation as (−∞,∞).

For example, the function Start Power, Start base, x , base End,Start exponent, 2 , exponent End , Power Endx2 takes the reals (domain) to the non-negative reals (range). The sine function takes the reals (domain) to the closed interval [-1, 1]-1, 1 (range)....

Avoid confusion about open and closed intervals when finding the domain and range of a function. If the endpoint is not included (e.g., division by zero), then use the parentheses ( ) If the endpoint is included (e.g., square root boundary), then use the brackets [ ] Example: [5, ∞) means x = 5 is included, while (5, ∞) means it is not included. To learn how to convert inequity and value sets into an interval notation form, try our interval notation calculator.

The Domain of a function is represented by the set notation, for example, Df={ x : a<x<b }. The Domain can be calculated using the function definition or the constraints that define the function.
