Precalculus With Limits: A Graphing Approach Apr 2026

Graphing is easier when you view equations as "shifts" of the parent functions. Horizontal Shifts: (Right) or Reflections: (Over x-axis) or (Over y-axis) Scaling: stretches or shrinks the graph vertically. 3. Analyze Polynomial & Rational Functions

Identify Amplitude (height), Period (length of one cycle), and Phase Shift (horizontal slide). Identities: Use Pythagorean identities ( ) to simplify expressions before graphing. 5. Limits: The Bridge to Calculus Precalculus with Limits: A Graphing Approach

These determine the horizontal asymptotes of the graph. 🚀 Study Tips Graphing is easier when you view equations as
