Answer:
The minimum value for is .
Step-by-step explanation:
Given function is
We need to find the maximum value or the minimum value for the function.

Now, we will equate to find critical point.
Plug this critical point in to the function we get,
Also, which is positive, We have minimum value.
So, the minimum value for is .
