Graph each parabola by hand, and check using a graphing calculator. Give the vertex, axis, domain, and range.
\n" ); document.write( "x = -2y2 + 2y - 3
\n" ); document.write( "complete the square:
\n" ); document.write( "x=-2(y^2-y+1/4)+1/2-3
\n" ); document.write( "x=-2(y-1/2)^2-5/2
\n" ); document.write( "(y-1/2)^2=-(1/2)(x+5/2)
\n" ); document.write( "This is a parabola that opens leftward:
\n" ); document.write( "Its basic form of equation: (y-k)^2=-4p(x-h), (h,k)=(x,y) coordinates of the vertex.
\n" ); document.write( "For given parabola:
\n" ); document.write( "4p=1/2
\n" ); document.write( "vertex:(-5/2,1/2)
\n" ); document.write( "axis of symmetry: y=1/2
\n" ); document.write( "domain: (-∞,5/2]
\n" ); document.write( "range: (-∞,∞) \n" ); document.write( "
\n" );
