Question

how to solve d/dx g(f(x)), x=1

Answer 1

Its just the chain rule

Answer 2

If the question asks: Let f and g be functions such that f(1)=2, g(1)=3, f'(1)=-2, g'(1)=4, and g'(2)=-3. Find the following values. How would you use the chain rule?

Answer 3

Its g'(f(x))f'(x)

So g'(f(1))f'(1)

Answer 4

Now start substituting for instance f(1) = 2 so
g'(f(1))f'(1) = g'(2)f'(1)
