function plotFunc(f,x_min,x_max)

f is a function handle.

Hi!

to define your function you can use the inline() command and then to plot you can use the fplot() command. Your code may look something like this.

f = inline('x^3')  %  This creates an inline function
fplot(f, [-1, 1])  %  This will plot the inline function f from the limits    %set in the second input.  Then you can edit the plot area anyway that you   %would like (add axis labels and a title)

Hope this helps

Cheers,

Rhys

Edited to make it look nicer.

It seems that the function you want to make is the same as fplot.
