If `int((x-1)/(x^2))e^x\ dx=f(x)\ e^x+C ,` then write the value of `f(x)` .

Explanation

To solve the problem, we need to evaluate the integral

\[ I = \int \frac{x-1}{x^2} e^x \, dx \]

and express it in the form \( f(x) e^x + C \), where \( C \) is a constant. Our goal is to find the function \( f(x) \).
