Explanation
## Step 1: Find the derivative of the function### To find the critical points, we need to take the derivative of the function
. The derivative is
.## Step 2: Find the critical points### Set the derivative equal to zero and solve for
:
. This critical point lies within the interval
.## Step 3: Evaluate the function at the critical point and endpoints### Evaluate the function at the critical point
and the endpoints
and
:
## Step 4: Determine the absolute minimum### Comparing the values
,
, and
, the absolute minimum value is
