] | First take the derivative:
$f'(x)=2x-2e^{-2x}$
Now consider the values when the derivative is equal to 0:
$2x-2e^{-2x}=0$
Now the function is increasing whenever $f'(x)$ is positive, and decreasing when it is negative. I.e., $f$ is increasing when:
\begin{align\*}
2x &> 2e^{-2x}\\
x &> e^{-2x}\\
\ln(x) &> -2x
\end... | $\frac{\delta f(x)}{\delta x}=-2e^{-2x}+2x$
Thus, the function is increasing when:
$2x>2e^{-2x}$
$x>\frac{1}{e^{2x}}$

The `Bitmap` is derived from `Image` so you can use Icon's `.ToBitmap()` method.
### Sample
```
Icon IEIcon = Icon.ExtractAssociatedIcon(@"C:\Program Files\Internet Explorer\iexplore.exe");
Image im = IEIcon.ToBitmap();
