    its about finding regions and stuff...
    so yeah

    a:y>=-4 x=<3 y<x
    b:x<0 y=<2 y>=x-3
    c:x>1 y=<2 y>=x
    d:y=<5 y>=x y>=-x
    e:y<4 y>=x+1 y>=1-x
    f:y>=x y=<2x y<3

    HALP!!!

    Maybe these are like "feasible regions" in a linear programming model!?

    Well the domain of the first one is...

    -4 < x <= 3

    And the range is...

    -4 <= y < 3

    You mean that?
