Plot the following expression in the Function app:

x^(1/3)*(x+3)^(2/3)

The resulting plot is only partialy shown... values should be plotted for x < -3 as well. I assume this has something to do with the way the Prime handles exact/inexact arithmatic?

Both Mathematica and a textbook confirm the plot should display values for x < -3

I'll try to remember to upload a screen shot when I get storage space on this site.

Done.

I've plotted the expression two ways (working horizontally in the figure):

The first row shows the Mathematica output, the Prime equation, and Prime output. Same for the second row, just rewrote the expression. Both Prime plots seem to disagree with Mathematica's plot.
