Vocabulary
• Absolute Value Function – a piecewise function, written as f(x)= ,
where f(x) 0 for all values of x.
• Greatest Integer Function – a step function, written as f(x) = [x], where f(x) is the greatest integer not greater than x.

• Piecewise Function – a function in which different equations are used for different intervals of the domain.
• Step Function – a function whose graph is a series of disjoint lines or steps.
