Understanding function transformations in graphs is essential for mastering how different mathematical operations affect graph shapes and positions.

  • The transformations include vertical and horizontal shifts, reflections across axes, and stretching or compressing graphs
  • Each transformation follows specific rules that modify either x or y coordinates
  • Vertical transformations affect y-coordinates while horizontal transformations affect x-coordinates
  • Reflections can occur across both x and y axes, creating mirror images of the original function
  • Stretching and compression factors determine how the graph expands or contracts

Function Transformations and Their Effects

This comprehensive page details various effects of function reflections and stretches on graphs, providing a systematic breakdown of common transformations.

The transformations are organized into several categories:

Definition: Vertical shifts (y = f(x) + a) move the graph up when a is positive and down when a is negative.

Definition: Horizontal shifts (y = f(x + a)) move the graph left when a is positive and right when a is negative.

Highlight: Reflections can occur in two ways:

  • y = -f(x) reflects the graph across the x-axis
  • y = f(-x) reflects the graph across the y-axis

Example: When dealing with stretches and compressions:

  • For y = kf(x): k > 1 creates a vertical stretch, k < 1 creates a vertical compression
  • For y = f(kx): k > 1 creates a horizontal compression, k < 1 creates a horizontal stretch

Vocabulary:

  • Stretch: Expansion of the graph along an axis
  • Compression: Contraction of the graph along an axis
  • Reflection: Mirror image of the graph across an axis

This graph function compression and stretching explained guide serves as a fundamental resource for understanding how mathematical operations transform basic functions into more complex forms.
