#12

Read 4.2.
Prob A:  If f(x) = c u(x), prove f '(x) = c u'(x) by definition of derivative.
4.1; 43, 57, 58abcd, 62, 71.  (Hints below; remember to include units in 62 and 71)
4.2; 7, 19, 22, 29, 30, 33.   (Instructions specify use product or quotient rule, so you must!)
Hint for 4.1 probs:  Easier not to use quotient rule, instead pull constants out front and/or use negative exponents.
Hint on 56d: Units of BMI are just that, units of BMI. Describe the derivative as how much something changes for every what?
Optional star (hand in separately within a week): do the pair of problems *(4.1;65 and 4.2;37 ).
