Key Concepts

Vertical Scaling

Vertical scaling is a transformation that multiplies the output of a function by a constant factor. This affects the graph by stretching or compressing it vertically. When applied to a step function like the floor function, it scales the heights of the steps while preserving the positions of the jumps.

Graphing Piecewise Functions

Graphing piecewise functions involves plotting each segment or constant piece of the function on its corresponding interval, while clearly indicating any discontinuities using open or closed circles. This method is effective for functions like the floor function, which exhibit distinct sections with abrupt changes.

Floor Function

The floor function, often denoted by [x] or ?x?, maps any real number to the largest integer less than or equal to that number. It is characterized by its step-like behavior, remaining constant over intervals and jumping at integer boundaries.

Step Function

A step function is a type of piecewise constant function that takes on a constant value within each interval of its domain, with sudden jumps between these intervals. The floor function is a common example of a step function due to its discontinuities at integer values.
