What is the definition of 'Domain' in a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) that will not cause any mathematical errors such as division by zero or taking the square root of a negative number.

What is the definition of 'Range' in a function?

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that result from substituting the domain values into the function.
