MHB Possible title: How to Find the Derivative of y=e-.5x?

[coolbeans33]

what are the steps in finding the derivative of the function y=e^-.5x

and why is the answer zero?

sorry I'm posting like 150 threads, I'm just really bad at math.

$$\frac{dy}{dx} \ne 0$$. What have you tried? In general, what is $\dfrac {d}{dx} e^{x}$? What about $\dfrac{d}{dx} e^{f(x)}$?

Also, 2k posts! :D

Uh?
The answer is not zero.

The steps are the application of the chain rule.
Combined with the rule that the derivative of $e^x$ is $e^x$.

Didn't you just apply the chain rule in your previous thread?
Rather successfully in a more complicated problem I might add?
