write the equation of a parabola that opens upward with an axis of symmetry of x=-7/2...
\n" ); document.write( "this means that -b/(2a) = -7/2\r
\n" ); document.write( "\n" ); document.write( "I can assume that a = 1, b = 7 here.\r
\n" ); document.write( "\n" ); document.write( "we would not know c...\r
\n" ); document.write( "\n" ); document.write( "f(x) = x^2 + 7x is one possible equation for this parabola.\r
\n" ); document.write( "\n" ); document.write( "in general, we can say that the equation for the parabola is g(x) = x^2 + 7x + c for c is any real number.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
