What is a step function?

Back

A step function is a piecewise constant function that jumps from one value to another without taking on any values in between.

How do you identify a piecewise function from a graph?

Back

You can identify a piecewise function from a graph by looking for distinct segments or pieces that correspond to different intervals of the x-axis.

What is the absolute value function?

Back

The absolute value function is a function that returns the non-negative value of a number, defined as f(x) = |x|.

What is the general form of a piecewise function?

Back

The general form of a piecewise function is f(x) = { expression1 for x in interval1, expression2 for x in interval2, ... }.

Front

What is the domain of a piecewise function?

Back

The domain of a piecewise function is the union of the domains of each piece or segment of the function.

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

Back

To evaluate a piecewise function at a given point, determine which interval the point falls into and use the corresponding expression.

What is the difference between continuous and discontinuous piecewise functions?

Back

Continuous piecewise functions have no breaks or jumps in their graphs, while discontinuous piecewise functions have breaks or jumps at certain points.

How can you graph a piecewise function?

Back

To graph a piecewise function, plot each piece according to its defined interval and connect the points appropriately.
