I noticed that the Advanced Graphing app fails to find extrema and inflections in the fairly basic function:

Y=e^(-X)*(X+3) or its inverse.

However, Y=2^(-X)*(X+3) and Y=3^(-X)*(X+3) work fine.

It seems to be an integer verses decimal issue as Y=2.001^(-X)*(X+3) also fails.

You may be right on that because:

Y=((419314/154257))^(-X)*(X+3)

works.

Thanks, Wes. We will look into this.

The bug seems to have been introduced early on in the firmware.
