$\"\"$

\

The function is $\"\"$ .

\

Rewrite the function as $\"\"$ .

\

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

\

Recall the derivative of the exponential function : $\"\"$ .

\

$\"\"$ .

$\"\"$

\

Find extrema by equating the first derivative to zero.

\

$\"\"$

\

It is never possible, because $\"\"$ and $\"\"$ are never zero.

\

Hence the function $\"\"$ has no extrema.

\

$\"\"$

\

For inflection points, equate second derivative to zero.

\

Consider $\"\"$

\

Apply derivative with respect to $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Substitute $\"\"$ in the original function.

\

$\"\"$

\

Thus, the inflection point occurs at $\"\"$ .
