Question
![Let \( f(x) \) be a function that is defined and has a continuous derivative on the interval \( (2, \infty) \). Assume also that
\[ f(3) = -14 \]
\[ |f(x)| < x^7 + 10 \]
and
\[
\int_{3}^{\infty} f(x) e^{-x/7} \, dx = 4
\]
Determine the value of
\[
\int_{3}^{\infty} f'(x) e^{-x/7} \, dx
\]
The problem involves finding the value of an integral that includes the derivative of the function \( f \). Given that \( f(x) \) has certain properties, including a bound and a specific integral value, you have sufficient information to solve for the desired integral.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fccac55ee-732b-4607-a38e-f5bd0a8aacb2%2F45cef1c7-07be-486f-b29a-031a7eb1a507%2F5jcplku_processed.png&w=3840&q=75)
