Precalculus With Limits: A Graphing - Approach

If a graph looks weird, plot 3-5 specific points to anchor it.

Always check for "illegal" math (denominators of zero or negatives in square roots). Precalculus with Limits: A Graphing Approach

Before graphing complex equations, you must recognize the "parent" functions by sight. (Diagonal line) Quadratic: (U-shaped parabola) Cubic: Absolute Value: Square Root: (Starts at origin, curves right) Reciprocal: (Hyperbola with asymptotes) 2.
