What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What are domain restrictions?

Back

Domain restrictions are limitations on the input values of a function, often due to factors like division by zero or square roots of negative numbers.

How do you find the domain of a function?

Back

To find the domain, identify any values that would make the function undefined (like division by zero) and exclude them from the set of all real numbers.

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does it mean for a function to be defined?

Back

A function is defined for a particular input if it produces a valid output without any restrictions.

What is the difference between open and closed intervals?

Back

An open interval (a, b) does not include the endpoints a and b, while a closed interval [a, b] includes both endpoints.
