I need to find the absolute minimum value of on the interval (0, infinity). I took the first derivative, and set it equal to zero. I found that x= 4, but I don't think that's the absolute minimum. Please help!!!

I found that x= 4, but I don't think that's the absolute minimum. Please help!!! Go back and re-work - carefully - your solution to f'(x) = 0.
I reworked the problem and got and x=2 but I still don't think that 2 is the absolute minimum value. How should I check it?
You're wrong again...
f'(2) does not equal 0 check again
