-intercepts (Zeros): These are found by setting the numerator after simplifying. -intercepts: Calculated by finding 2. Determine End Behavior Topic 1.7 emphasizes how the function behaves as
In the context of AP Precalculus, the review for (which often appears in combined review packets like "Review A: Topics 1.7–1.11") focuses on the fundamental behavior of Rational Functions . 1. Identify Key Components A-1.7z
: There is no horizontal asymptote (the function increases or decreases without bound). 3. Apply Limit Notation -intercepts (Zeros): These are found by setting the
To master Topic 1.7, you must be able to solve for , determine horizontal behavior through degree comparison, and express these findings using formal limit notation . Apply Limit Notation To master Topic 1
To review Topic 1.7 properly, you must be able to identify these features of a rational function These occur at the -values where the denominator (and does not cancel with the numerator).
A "proper" review requires using formal limit notation to describe the behavior near asymptotes and at the ends: Horizontal Asymptote at : 4. Example Problem Consider the function Vertical Asymptote: Set Horizontal Asymptote: Degrees are equal ( Zero: Set End Behavior: ✅ Summary
