Sketch a narrow parabola tha spills water and has a turning point of (0, -4). Will this parabola have real or complex roots
\n" ); document.write( "-------------------
\n" ); document.write( "Have you grandson plot the point (0,-4) on the y-axis of an
\n" ); document.write( "x/y coordinate system.
\n" ); document.write( "If the parabola spills water it must look like a goblet that
\n" ); document.write( "is upside-down; draw an upside-down parabola that has its
\n" ); document.write( "high point (vertex) at (0,-4).
\n" ); document.write( "Notice that this parabola does not intersect the x-axis.
\n" ); document.write( "That means it has two complex roots.
