Horizontal And Vertical Graph Stretches And Compressions (Part 1)
The general formula is given as well as a few concrete examples.
- y = c f(x), vertical stretch, factor of c
- y = (1/c)f(x), compress vertically, factor of c
- y = f(cx), compress horizontally, factor of c
- y = f(x/c), stretch horizontally, factor of c
- y = - f(x), reflect at x-axis
- y = f(-x), reflect at y-axis

Effects On The Parent Function
In this video we discuss the effects on the parent function when:
- Stretched Vertically,
- Compressed Vertically,
- Stretched Horizontally,
- Compressed Horizontally.
Different Types Of Math Transformation
There are different types of math transformation, one of which is the type y = f(bx). This type of math transformation is a horizontal compression when b is greater than one. We can graph this math transformation by using tables to transform the original elementary function. Other important transformations include vertical shifts, horizontal shifts, and reflections.
This video reviews function transformation including stretches, compressions, shifts left, shifts right, and reflections across the x and y axes.
