Enclosing(MS of curves f, pointg)

make PD of the closed curve connecting the nearest intersection of
adjacent curves in order. If the first curve and the last curve intersect
at more than one points, “point” should be indicated. The closed
curve begins from the intersection nearest to “point”.
Ex) G1=Plotdata( xˆ2 , x );
G2=Plotdata( 2-x , x );
G3=Plotdata( 2+x , x );
G4=Enclosing(Mix(G1, Invert(G2), Invert(G3)), [-1, 1] );
“Invert” is to be described.
