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 .
Graph :
\Draw a coordinate plane.
\Graph the function .
Observe the graph :
\There is no extrema for .
The inflection point occurs at .
The inflection point occurs at .
