Need to Know: the vertex form of a Parabola opening up(a>0) or down(a<0):
\n" ); document.write( " $\"y=a%28x-h%29%5E2+%2Bk\"$ where(h,k) is the vertex and x = h is the Line of Symmetry\r
\n" ); document.write( "\n" ); document.write( "Y= $\"highlight_green%282%29\"$ (x+1)^2-4
\n" ); document.write( "Upward a = 2 > 0
\n" ); document.write( "V(-1,-4), axis of symmetry: x = -1
\n" ); document.write( "
