Does there exist some functions that can solve inequality equations?

Recently, I want to solve a series of nolinear inequality equations but I can not find any functions that can be used to solve inequality equations.I know they can be solved by drawing the image of them combined with the use of the function"solve".However, since the process is adaptive, I can not pick the intervals by myself, it should be done by the program. Do you guys have other ways to solve this kind of problem? Any answers will be appreciated.

Solving linear inequality is complicated, non linear will make them more complicated. for now, There are no function that can do that
