$\"\"$

(a)

The function is $\"\"$ .

Find the critical numbers by applying derivative.

$\"\"$

Apply derivative on each side with respect to $\"\"$ .

$\"\"$

Equate the derivative to $\"\"$ .

$\"\"$

Critical number is $\"\"$ .

$\"\"$

(b)

Consider the test intervals to find the interval of increasing and decreasing.

Test intervals are $\"\"$ and $\"\"$ .

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

The function $\"\"$ is increasing on the intervals $\"\"$ and $\"\"$ .

$\"\"$

(c)

Use first derivative test to identify all relative extrema.

The function is increasing function so it does not have any exreme points.

$\"\"$

(d)

Graph the function is $\"\"$ .
