Topic: Graphing trouble!

Hi, Ivan!

I'm working with:

f(x) = x^(8/9)-x^(17/9); I want a plot for it.

Using Maple16, I got the picture on it.

You can see the graph you get using Graph 4.4

> f(x):=((8)/(9 x^(1/9))-17/9 x^(8/9));

           
> f(-1.)

                  2.610257281 - 0.9500559537*i
> f(-2.)

                  4.060175631 - 1.477783074*i
> f(-3.)

                  5.452326391 - 1.984484514*i


Could you, please, tell me which is correct?

Thanks a lot, in advance, for your time!

Best regards,

Guillermo Garcia.

Re: Graphing trouble!

I am not sure what it is you are doing. Which of the two functions are we talking about and what is the exact problem?
