Scribe Post

Hey guys, it's Lindsay again. We started class with the usual white board questions. For some of the questions we used the
CHAIN RULE:
F(x) = f(g(x))
F'(x) = f'(g(x))g'(x)

1. Differentiate.




































2. f(x) xe^-3x
a) find f'












b) find f"











c) determine the interval(s) where f is increasing
(-infinity, 1/3)
d) determine the interval(s) where f is concave up
(2/3, infinity)

3. Given the equation below, solve for y and differentiate
x² + y² = 25






IMPLICIT means that it's SUGGESTED without having it IN YOUR FACE!
A circle isn't a function but we can still find the derivative for it by looking at one section of it.
