Today's Goal: Solidify our understanding of limits and the derivative 1
Problem 1: Evaluate the limit, if it exists. 1. lim x → 5 (2 + 2 x 3 ) 2. lim x → 6 | x − 6 | 3. lim x → 3 1 x − 3 4. lim x → 4 p 4 x 2 + 5 5. lim x →∞ 7 x 6. lim x →∞ 9 x 2
Problem 2: Consider the graph of the function f ( x ) : At which x-values does the limit of f ( x ) exist? At which x-values is the function differentiable? 3
