Equations - Horizontal Shifting

Horizontal Shifting

Definition and Effect on Graphs

A horizontal shift changes the position of a graph left or right on the coordinate plane. It is represented by the transformation: \[ g(x) = f(x - C) \] where \( C \) is a constant.

How It Works

  • If \( C > 0 \), the graph shifts to the right by \( C \) units.
  • If \( C < 0 \), the graph shifts to the left by \( |C| \) units.
  • The shape and size of the graph remain unchanged — only the position along the x-axis is altered.

Applications

  • Used in graph transformations for functions and equations.
  • Important in modeling time delays or advances in physics and engineering.
  • Common in wave function manipulations and animations.
