What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas for different parts of its domain.

How do you evaluate a piecewise function at a specific point?

Back

To evaluate a piecewise function at a specific point, determine which piece of the function applies to that point and then use the corresponding expression.

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 does it mean if a piecewise function has a domain restriction?

Back

A domain restriction means that the function is only defined for certain values of x, excluding others.

What is the range of a piecewise function?

What is the difference between an open interval and a closed interval in the context of piecewise functions?

Back

An open interval does not include its endpoints, while a closed interval includes its endpoints.
