Rational Inequalities
Answered
Does Geogebra calculate inequalities for just polynomial functions? I have noticed simple commands as x^22<0 will shade in or place a solution on graphics. However if you type in x/(x1)<0, this will show up as a function. Moreover, exponential and sinusoidal functions do not work for inequalities either.
My end goal is to create a program that can take any two rational functions f(x), and g(x) and solve f(x)<g(x) etc and output the answer either visually or via text. My program currently works for f(x) and g(x) being polynomials (haven't figured out the text tho).

About a rational inequality, you can solve it in CAS view, or in Algebra View with a workaround.

Or this, also
Ah, this is a simple solution!
Thank you both!
thank you mathmagic
is there a way to write the borders of the solution of the inequalities  in other words to make the xvalues as independent numbers so we can print the solution and use them as Objects?
do you mean f(x)==g(x)?
there is not a general method for all functions. try intersect,solutions, Nsolutions, CAS etc
they work depending of functions you wan
an example could help
when you have a set of points you can use x(setofpoints) for x coords
