was it also said that you would treat c as another variable? because in most problems, c is treated as a constant.
thus:
f'(x) = c
g'(x) = c
Differentiate.
y = (cx)/(1 + cx)
g(x) = 1 + cx
f(x) = cx
Using the quotient rule:
y' = [(1 + cx)(f') - (cx)(g')]/(1 + cx)^2
How do you find f' and g' when there is more than one variable? Having a C and an X?
