I need this equation graphed also need to find the coordinates of the vertex.
\n" ); document.write( "The problem is y= -x^2 - 8x - 7
\n" ); document.write( "----------------------
\n" ); document.write( "You could answer this by completing the square or
\n" ); document.write( "by doing the following:
\n" ); document.write( "-------------------------------
\n" ); document.write( "The vertex occurs where x = -b/(2a) = 8/(2*-1) = -4
\n" ); document.write( "The corresponding y-value is f(-4) = -16 +32 -7 = 9
\n" ); document.write( "The vertex is (-4,9)
