Answer:
option A would be correct.
Step-by-step explanation:
The only pairs of function \(f(x)=x^2\) and \(g(x)=\frac{1}{x}\) satisfying (f•g)(x)=x.
Check:
\(\left (f\cdot g\right )(x)\)\(=f\left (x\right )g(x)\)
= \(x^2\cdot \frac{1}{x}\) = \(x\).
(f•g)(x)=x.
Therefore, from the options only Option A would be the required answer
