Given information
The given equation is
Step-by-step explanation
Step 1.
To find the absolute extrema points. Evaluate the value of at each of the critical points and also the end points. Out of these, the maximum value of is absolute maximum. And, the minimum value of is absolute minimum. Note that there will be only one absolute maximum and one absolute minimum. Also note that all this is true only when the intervals are closed.
Finding the critical numbers
Critical points of are the values of for which does not exist, or if it exists it is zero.
when
Therefore the critical numbers are
Note that these points lie in the given interval
The end points are
To determine absolute extrema points, we should find
