Hence, Option E is correct.
F) ; which is not same as expression (1)
Hence, option F is incorrect.
For convenience sake, I will let
First, we evaluate the function at the endpoints of the interval.
Then, we need to find the critical points.
We can start by taking the derivative using the power rule.
Setting this equal to 0,
Since , we can divide both sides by
.
So, the absolute minimum is and the absolute minima are
