Look at the help files for the plot command. Type, or cut and paste the code below, and hit the enter key, or open the help browser and search for plot.

?plot

This is how you would define a function of x, using your first example. Notice that I put a multiplication sign after the 9.

f:=x->x^3+3^2-9*x+5;

so after doing the above, if you enter;

f(3)

Maple will answer with

The help files have examples exactly like what you are trying to do. Start there, and see how far you get.

Once you have created the procedure f, as Georgios described, you can plot it with

plot(f, 0..1);

where the 0..1 specifies the domain over which to evaluate f.

An alternative is to forego creating a procedure and instead use an expression. In that case you have to tell Maple what variable to vary:

ex := x^2+1:
plot(ex, x = 0..1);

sorry I didn't give all the information I am working on applications of the derivatie and using graphs

I need to analyze the graph by finding the relative minimum and relative maximum and the vertical asymptote point of inflection.

Here is the steps that i need to do

Determine the domain and range of the funciton

determine the intercepts and asymptotes of the graph

locate the x-vaules where f'(x) and f''(x) are zero or undefined

then determine where the relative extrema and the points of infection occur.

I hope this software can help me do this because I was sick for a week and have missed the classes that taught this information.

thanks for any and all help
