Section 5.2.3 Day 2 Limits Review
Lesson Objective: Students will: • Understand the necessary conditions for a limit to exist. • Practice finding limits. • Predict limits from tables.
(1).General Idea: Behavior of a function very near the point where (2). Layman’s Description of Limit(Local Behavior) L If x approaches a, from both sides, then the function approaches a single number, L. a (3). Notation (4). Mantra
4 Ways to Depict Limits G N A W Graphically Numerically Analytically Words
G N A W Graphically
FINDING LIMITS • Graphically
G N A W • Numerically • Words Mantra:
FINDING LIMITS • Analytically Rem: Always start with Direct Substitution
FINDING LIMITS • Analytically
(2). If a is not in the domain: Start with Substitution A. If the result is , ( this step must be shown), then factor and substitute again.
Graphically Since the function is undefined at x = 3, this produces a “hole” in the graph.
(2). If a is not in the domain: Start with Substitution B. If the result is , ( this step must be shown), then factor and substitute again.
Graphically Since the function is undefined at x = 3, this produces a “hole” and an asymptote in the graph.
