Polynomial graphs

Can Graphing Calculator 3D plot polynomial graphs? I tried graphing this:

3x^3+x^2+5x+5

But it gave invalid input error msg!

Yes it can plot polynomial functions, however don't forget to put multiplication sign (*). In your example you missed the multiplication operator. You should type this instead:

3*x^3+x^2+5*x+5

Try it and let me know how it went.

sweet! it worked like a charm
