Function Notation and Composition

Using the form y = a f(bx) encapsulates both vertical and horizontal scaling in a single algebraic expression. Here, the constant 'a' determines the vertical stretch or compression (and potential reflection), while 'b' governs the horizontal stretch or compression (and potential reflection), providing a systematic way to describe and perform these transformations.

Graph Transformations

Graph transformations refer to the changes made to a function's graph that alter its position, shape, or orientation. These include operations such as translations (shifts), reflections, and scaling (stretching or compressing) of the function without changing its basic structure.

Vertical Scaling

Vertical scaling involves multiplying the output of a function by a constant. This transformation stretches the graph vertically if the absolute value of the constant is greater than one or compresses it if it is between zero and one. If the constant is negative, it also results in a reflection across the x-axis.

Horizontal Scaling

Horizontal scaling is achieved by multiplying the input (or the variable within the function) by a constant. This transformation compresses the graph horizontally when the absolute value of the constant is greater than one and stretches it when the absolute value is between zero and one. A negative constant will additionally reflect the graph across the y-axis.
