please solve C only

Q2 What is the feasible region for x given the following constraints? Sketch the feasible region for the two-dimensional problems. a) h1(x)=X1+X23=0 h(x)=2X1X2+1=0 b) h(x)=X1+X=3 g(x)=X1X:20g(x)=X10g(x)=X20 c) Chemical reactions are given H2O+CO2H2CO2 CO2CO Assuming that H2O,C and O2 are available. The objecture is to prove whether H,CO1 can be performed given that H,O,C and O, are available. Hint: Define binary variables corresponding to each C,O,CO and H,CO
