Find the x-value for the vertex and that is the axis.
\n" ); document.write( "x=-b/2a, where b is 7 and a is 1
\n" ); document.write( "The vertex has an x-value of -7/2. You don't even need the y-value. The axis of symmetry is x=-3.5
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2Cx%5E2%2B7x%2B6%29\"
