\n" ); document.write( "Using the vertex form of a parabola, \"y=a%28x-h%29%5E2+%2Bk\" where(h,k) is the vertex
\n" ); document.write( " y = 2x^2 - 8x - 1 ||Note the use of ^(uppercase 6) to signify the exponent
\n" ); document.write( " y = 2(x-2)^2 - 8 - 1 || completing the Square
\n" ); document.write( " y = 2(x-2)^2 - 9 || V(2,-9)min, a = 2>0, Parabola opens Upward, Range is y≥ -9, domain x is (−∞,∞)
\n" ); document.write( " \n" ); document.write( "
