Read 3.3. (Also, do the 3.4 problems listed at the bottom.)  Remember units in applications.
3.3; 6, 20, 25, 33, 34, 44.  You are required to follow the instructions below:
On 20, use limit with algebra.
On 25, use a table of values as on p. 158.
On 34c, graph the function and get derivative from a graph tool (On TI89 graph, F5 Math, Derivative; On Desmos, can ask for f '(a)).
3.4; 8, 9, 10.  (Since tangent line is drawn in, just take two convenient points, fairly far apart, to find slope of line.)
