Use a graphing calculator to verify your hand-drawn sketches, not replace them.
These determine the horizontal asymptotes of the graph. 🚀 Study Tips Precalculus with Limits: A Graphing Approach
Find x-intercepts and determine "multiplicity" (does the graph cross or bounce?). Asymptotes: Vertical: Where the denominator equals zero. Use a graphing calculator to verify your hand-drawn
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 Period (length of one cycle)
The "Limit" describes the behavior of a function as it approaches a specific point.
