The calculator can calculate numerical values of derivatives of functions (at a given point). It does not have a Computer Algebra System so what you want to do cannot be done. You should look for a Casio calculator with a CAS, such as the ClassPad, the FX_Algebra 2 or the FX 9860G. Sorry.

The solution set of a linear inequality in two variables (x,y) is one half of the Cartesian plane. The half-plane may or may not contain the boundary line defined by the = sign. Thus it is expected that the calculator shades the relevant half-plane. If you are dealing with nonlinear inequalities the calculator shades inside or outside the curve.
When drawing multiple inequalities the Casio offers you the possibility to shade the regions where ALL conditions (ALL inequalities) are simultaneously satisfied. The other option is OR.
If you are not interested in the shading do not draw inequalities, draw equations (with =).
