Question

Let f(y) = e^y + e^(2y). Find f ', the derivative of f.

Answer 1

using prodcuct rule - do you know?

Answer 2

No, I don't think that's it.

Answer 3

lets try this
\[ f(y) = e^y + e^{2y}\]
\[f'(y)=e^y+2e^{2y}\]

Answer 4

first because
\[\frac{d}{dx}e^x=e^x\] second by the chain rule

Answer 5

satellite - so the 1st derivative of e^x is still e^x

Answer 6

why wouldd the 2nd term not be 2e^y...
