\

The curve is $\"\"$ and inflection point is $\"\"$ .

\

Inflection point is a point of the curve where the curve changes from up to down or down to up.

\

Substitute $\"\"$ in the curve equation.

\

$\"\"$

\

Rewrite the curve.

\

$\"\"$

\

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

\

$\"\"$

\

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

\

$\"\"$

\

\

Find the values of $\"\"$ and $\"\"$ .

\

Inflection point is $\"\"$ .

\

Equate $\"\"$ to zero and substitute $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$ and $\"\"$ .

\

$\"\"$ and $\"\"$ .

\

Substitute $\"\"$ in equation (1).

\

$\"\"$

\

Substitute $\"\"$ in equation (1).

\

$\"\"$

\

\

Find the additional inflection points.

\

$\"\"$

\

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

\

$\"\"$

\

No inflection point is obtained, so $\"\"$ and $\"\"$ are not consider.

\

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

\

$\"\"$

\

Find the inflection points.

\

Equate $\"\"$ to zero.

\

$\"\"$

\

$\"\"$ and $\"\"$

\

$\"\"$ and $\"\"$ .

\

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

\

$\"\"$ and $\"\"$ .

\

\

The curve is $\"\"$

\

Substitute $\"\"$ and $\"\"$ in the above curve.

\

$\"\"$

\

The obtained curve is $\"\"$ .

\

Substitute $\"\"$ in the above curve.

\

$\"\"$

\

Substitute $\"\"$ in the above curve.

\

$\"\"$

\

Substitute $\"\"$ in the above curve.

\

$\"\"$

\

The inflection points are $\"\"$ , $\"\"$ and $\"\"$ .

\

Therefore the additional inflection points are $\"\"$ and $\"\"$ .

\

\

$\"\"$ and $\"\"$ .

\

The additional inflection points are $\"\"$ and $\"\"$ .
