Working with the chain rule. Have two sets of problems, and I have no idea how to even get started. VERY confused/frustrated. Here are my two problem sets:

Code:

Suppose k '(1) = 4.
(a) If f(x) = k(7x), find f '(1/7).
f '(1/7)=
(b) If g(x) = k(x+ 6), find g '(-5).
g '(-5) =
(c) If h(x) = k(x / 11), find h '(11).
h '(11) =

and

Code:

Suppose f(2) = 4 and f '(2) = 7. Find the derivatives
of the following functions.
(a) g(x) = sqrt(f(x))
g '(2)=
(b) h(x) = 1/f(x)
h '(2)=

If anyone can help me out it would be greatly appreciated. I have to turn this in by 11pm.
