anonymous · Answer

hahaha yup, i am quite sure, i even used the website you posted and came to the conclusion of having a "human" help me with this problem rather than a computer. I tried to do it by hand and was quite unsuccessful :(

experimentx · Answer

if there were no x^2 at the end then i could have helped you for sure!!!

anonymous · Answer

the problem i am trying to solve involve the question giving me this equation along with its graph, and thus it asked me to find the absolute maximum  and justify my answer.  So i thought i should take the integral of the first derivative to find its original in order to find the max

anonymous · Answer

the absolute max of f(x)

anonymous · Answer

the first derivative being the equation already given above

experimentx · Answer

is some interval given you to??

anonymous · Answer

yeah, the interval from 0-3

anonymous · Answer

mmm what do you mean by definite integral :P

experimentx · Answer

sorry ... that doesn't work!!!

anonymous · Answer

well the only other information give to me is that f(0)=5, but i am not sure as to how that will help

experimentx · Answer

are you university student??

anonymous · Answer

eh.....why?

experimentx · Answer

did you study numerical integration method???

experimentx · Answer

there's one way,
i am not sure if this method will work
$$ \int_{0}^{x} f(x) = F(x) - F(0)$$ 
Evaluate the integration using numerical method and find the value of F(x)... from 0 to 3, this is going to be computer's job rather than hand.

anonymous · Answer

Don't see how how f(0)=5.
