Answer:
![c=6](https://tex.z-dn.net/?f=c%3D6)
Step-by-step explanation:
The absolute maximum of a continuous function
is where
. Therefore, we must differentiate the function and then set
and
to determine the value of
:
![f(x)=xe^{-x}+ce^{-x}](https://tex.z-dn.net/?f=f%28x%29%3Dxe%5E%7B-x%7D%2Bce%5E%7B-x%7D)
![f'(x)=-xe^{-x}+e^{-x}-ce^{-x}](https://tex.z-dn.net/?f=f%27%28x%29%3D-xe%5E%7B-x%7D%2Be%5E%7B-x%7D-ce%5E%7B-x%7D)
![0=-(-5)e^{-(-5)}+e^{-(-5)}-ce^{-(-5)}](https://tex.z-dn.net/?f=0%3D-%28-5%29e%5E%7B-%28-5%29%7D%2Be%5E%7B-%28-5%29%7D-ce%5E%7B-%28-5%29%7D)
![0=5e^{5}+e^{5}-ce^{5}](https://tex.z-dn.net/?f=0%3D5e%5E%7B5%7D%2Be%5E%7B5%7D-ce%5E%7B5%7D)
![0=e^5(5+1-c)](https://tex.z-dn.net/?f=0%3De%5E5%285%2B1-c%29)
![0=6-c](https://tex.z-dn.net/?f=0%3D6-c)
![c=6](https://tex.z-dn.net/?f=c%3D6)
Therefore, when
, the absolute maximum of the function is
.
