Graphical Differentiation
Directions: Without finding explicit formulas for the functions
f(x) and g(x) whose graphs appear above,
use these graphs along with your knowlege of differentiation rules to
compute the following:
| (1) Let h(x)=(fg)(x).
| Find
| (a) h'(1)
| (b) h'(3).
|
| (2) Let h(x)=(g/f)(x).
| Compute
| (a) h'(3)
| (b) h'(1).
|
| (3) Let h(x) = g(f(x)).
| What is
| (a) h'(3)
| (b) h'(2).
