Q.#8
To date, we have used the standard form of the Chain Rule: [f(g(x)] = f'(g(x)) g'(x).
There also is an alternate form:
dy du
used by rewriting composition with:
du dx
dy
dx
u=g(x) for the inner function
y=f(g(x)) =f(u) for the outer function
For example, h(x) = f(g(x)) = (3x+5) ³ becomes y=f(u) = u³, where u = 3x + 5
Using the above, please find the derivative of h(x) = f(g(x)) = (3x + 5)³ using:
Final Answer
a) Standard Form of Chain Rule:
[f(g(x)]' = f'(g(x)) g'(x)
b) Alternate Form of Chain Rule:
dy dy du
dx du dx
