a)y+3=-(x+2)+1----->y+3=-x-2+1--->y=-x-4
\n" ); document.write( ":
\n" ); document.write( "b)y=-f(x)--> y=-(-x+1)--->y=x-1
\n" ); document.write( ":
\n" ); document.write( "c)y=f(-x)--->y=-(-x)+1--->y=x+1
\n" ); document.write( ":
\n" ); document.write( "d)(x,y)-->(-x,-y) -y=-(-x)+1--->y=-x-1
\n" ); document.write( "
\n" );
