\

a)

\

The function $\"\"$ and the interval is $\"\"$ .

\

Differentiate the function with respect to $\"\"$ .

\

$\"\"$

\

Find the critical numbers of $\"\"$ on $\"\"$ by setting $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Critical number is $\"\"$ .

\

$\"\"$

\

Find the value of $\"\"$ at the critical number $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Find the values of $\"\"$ at the end points of the interval $\"\"$ .

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Compare the three values of $\"\"$ to find absolute extreme of the function.

\

Absolute maximum value is $\"\"$

\

Absolute minimum value is $\"\"$

\

$\"\"$

\

b)

\

The function $\"\"$ and the interval is $\"\"$ .

\

Find the values of $\"\"$ at the end points of the interval $\"\"$ .

\

Since open interval is there at $\"\"$ , exclude that point.

\

$\"\"$

\

$\"\"$

\

Absolute maximum value is $\"\"$

\

$\"\"$

\

c)

\

The function $\"\"$ and the interval is $\"\"$ .

\

Find the value of the function at critical number $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Since open interval is there at $\"\"$ , exclude that point.

\

Absolute minimum value is $\"\"$ .

\

$\"\"$

\

d)

\

The function $\"\"$ and the interval is $\"\"$ .

\

Find the value of the function at critical number $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Since open interval is there at $\"\"$ , exclude that point.

\

Absolute minimum value is $\"\"$ .

\

$\"\"$

\

(a) Absolute maximum value is $\"\"$

\

Absolute minimum value is $\"\"$

\

(b) Absolute maximum value is $\"\"$

\

(c) Absolute minimum value is $\"\"$

\

(d) Absolute minimum value is $\"\"$
