What is a function domain?

The domain of a function is the set of all input values for which the function is defined. It is the set of all values that can be inserted into the function and produce a valid output.

How do I find domain of function?

To find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a negative number, or taking the logarithm of a negative number. Remove these values from the set of all possible input values to find the domain of the function.

What's a function domain example?

For the function f(x) = 1/x, the domain would be all real numbers except for x = 0 (x 0), as division by zero is undefined.
