![Master the Greatest Integer Function (Step Function) - How to Graph
Learn how to graph the greatest integer function (step function) and understand its transformations! This video breaks down the core concept of rounding down to the nearest integer and then demonstrates how various changes to the function affect its graph. Well go through 10 examples from easy to challenging, covering all major transformations.
In this tutorial, you will discover:
What is the Greatest Integer Function? Understanding the [[x]] notation and how it always rounds down to the previous integer.
Basic Step Function Graph: How to graph the parent greatest integer function, recognizing its stair-step pattern (closed on the left, open on the right).
Vertical Stretch/Shrink: How a coefficient in front of the function (a * [[x]]) stretches or shrinks the graph vertically.
Horizontal Shift: How changes inside the brackets ([[x + h]]) shift the graph left or right (opposite effect).
Vertical Shift: How a constant added or subtracted outside the brackets ([[x]] + k) shifts the graph up or down (same effect).
Reflections: How negative signs (-[[x]] or [[-x]]) reflect the graph over the x-axis or y-axis.
Horizontal Stretch/Shrink: How a coefficient inside the brackets ([[b * x]]) stretches or shrinks the graph horizontally (reciprocal effect).
Combining Transformations: Graphing functions with multiple transformations and understanding the order of operations.
This video is perfect for algebra and pre-calculus students learning about piecewise functions and transformations.
