Evaluating Piecewise Functions Review

Front

What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas for different intervals 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 interval the point falls into and use the corresponding expression to find the function's value.

What does it mean if a piecewise function is undefined at a certain point?

Back

If a piecewise function is undefined at a certain point, it means that there is no corresponding output value for that input in the function's definition.

How do you determine which part of a piecewise function to use?

Back

You determine which part of a piecewise function to use by checking the input value against the conditions specified for each piece.

Front

What is the significance of the domain in piecewise functions?

Back

The domain of a piecewise function specifies the input values for which the function is defined, and it can vary for different pieces of the function.
