The function is $\"\"$ .

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

$\"\"$

Again apply derivative on each side with respect to $\"\"$ .

Find the inflection points.

Equate $\"\"$ to zero.

$\"\"$

The inflection point is at $\"\"$ .

Substitute $\"\"$ in $\"\"$ .

$\"\"$

Therefore the inflection points is $\"\"$ .

Now substitute $\"\"$ in $\"\"$ .

$\"\"$

$\"\"$ does not exist.

The inflection points is $\"\"$ but $\"\"$ does not exist.
