Example Question #2 : Finding Derivatives

Let . What is ?

Possible Answers:

Correct answer:


We need to find the first derivative of f(x). This will require us to apply both the Product and Chain Rules. When we apply the Product Rule, we obtain:

In order to find the derivative of , we will need to employ the Chain Rule.


 We can factor out a 2x to make this a little nicer to look at.

Now we must evaluate the derivative when x = .

The answer is .
