f

and

g

are differentiable functions. If

g^{\prime}(a)=2, g(a)=b

and

f o g=I

, then

f^{\prime}(b)=\ldots \ldots

View answer and explanation

Correct option: A

\frac{1}{2}

Option A (

\frac{{1}}{{2}}

) is correct because it is the value of

f^{\prime}(b)

obtained by differentiating the composite function and using the given values.
