a) Just plug in 1 for the numerator and g(x) for the denominator in the quotient rule. b) \[ {\frac {1+k{{\rm e}^{s}}}{ \left( s+k{{\rm e}^{s}} \right) ^{2}}} \] assuming y is a function of s. c) Follows from \[ x^{n} = \frac{1}{x^n} \] and \[ \frac{d}{dx} x^n = nx^{n1} \]

is the quotient rule the same thing as the reciprocal part b?

What do you mean? The reciprocal rule is a special case of the quotient rule. You can use either one for part b, but it's easier to use the reciprocal rule.

The derivative of a sum is the sum of derivatives, so differentiate s and then differentiate k*e^s.

No! Don't forget the factor k!

YTheManifold Group TitleBest ResponseYou've already chosen the best response.0
k does not depend on s, so you can just leave it unchanged
