$\"y+=+2%28x+%2B+3%29%5E2+-+5\"$
\n" ); document.write( "This is a vertical parabola. Since the $\"a\"$ value is positive, the parabola opens upward.
\n" ); document.write( "Vertex: (h,k) for form: $\"y+=+a%28x+-+h%29%5E2+%2B+k\"$
\n" ); document.write( "Vertex: (-3,-5)
\n" ); document.write( "For the axis of symmetry, look at the x-value in the vertex.
\n" ); document.write( "Axis of Symmetry: $\"x+=+-3\"$
