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
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

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.

The next scribe is MARK
