Precalculus With Limits: A Graphing Approach -

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

Find x-intercepts and determine "multiplicity" (does the graph cross or bounce?). Asymptotes: Vertical: Where the denominator equals zero. Precalculus with Limits: A Graphing Approach

Use a graphing calculator to verify your hand-drawn sketches, not replace them. Identify Amplitude (height), Period (length of one cycle),
