The question is asking to find the derivative of the function:

y=4-7e^-x^9

I am confused because there are so many exponents. It would really help to see the work with the answer.

You have to be clearer.

Is it:

? ...

If yes, use the chain rule.

The derivative of

Sorry about the clearness. It is: 4- [7e^(-x^9)]

I understand how to use the chain rule to find that u=-x^9

What I need help on is actually seeing the work of the rest - Jul 13th 2011, 07:40 AMStarDancer19Re: Derivatives of Functions
Sorry about that, but the question I am asking is the first suggestion you had.

In your example you have

======================================

Alternatively:

You have

Both notations depict the chain rule so pick whichever is easier to understand - Jul 13th 2011, 08:10 AMHallsofIvyRe: Derivatives of Functions
