Question 9: Fund the derivative of the following using the chain rule

HINT: It does cross the x-axis, your job is to prove that it does! What
does the Intermediate Value Theorem say specifically?
CONCEPT CHECK: Without using a calculator, can you find ap-
proximately where it crosses the x-axis? Narrow down the domain over
which f crosses the x-axis: [a,b].
9) Chain Rule Expertise: So you think you "get" derivatives and the chain
rule? Show me. Find the derivative of
f(x) =
√1+x³ sin²(x²)
tan(e3x²) ln(1 + 2x)
HINT: There is an easier way to do it, then there is the "brute-
force" way to do it. Think carefully before diving in. (Use logarithmic
differentiation).
