Precalculus With Limits: A Graphing Approach File

The "Limit" describes the behavior of a function as it approaches a specific point.

Follow the line from both sides; if they meet at the same height, the limit exists. Algebraic View: Try direct substitution first; if you get , factor or rationalize. 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. The "Limit" describes the behavior of a function

Compare the degrees of the numerator and denominator. 4. Trigonometry via the Unit Circle Coordinates: Remember if you get
