Question

I WILL GIVE MEDALS TO WHOEVER ATTEMPS OR CAN FIGURE OUT MY QUESTION :D

Answer 1

Let be a continuous function defined on the interval [2, infinity[ such that
f(4)=14
|f(x)| < x^3+10
and
the integral from 4 to infinity f(x)*e^(-x/4) = -5
Determine the value of:
the integral from 4 to infinity f'(x)*e^(-x/4) = ?

Answer 2

my other guess is -20+(14/e)
