2. Evaluate each of the following limits: a. lim X4 i. ii. iii. 1 (x-1)2 3. Let f(x) = = x-4 Numerically (include a table that shows the approach from both sides) Graphically (sketch a carefully drawn and well-labeled graph) Algebraically (using reasoning similar to Section 2.3) 1 9 Sx + 2 x 1 x+3 x 3 x +7-2 b. lim a. Carefully sketch the graph of f. b. Find both one-sided limits and the two-sided limit, if they exist, for (x) as x 1.
