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 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 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.

How do you determine which equation to use in a piecewise function?

Back

To determine which equation to use, identify the input value and find the corresponding interval in the piecewise definition.

What is the significance of the 'top', 'middle', and 'bottom' labels in piecewise functions?

Back

These labels refer to the different expressions used in the piecewise function for different intervals of the input.

How do you graph a piecewise function?

Back

To graph a piecewise function, plot each piece according to its defined interval and ensure to use open or closed circles to indicate whether endpoints are included.
