You can put this solution on YOUR website!
For a function of the form $\"f%28x%29=ax%5E2%2Bbx%2Bc\"$ , the line of symmetry is the vertical line passing through the vertex. The x-coordinate of the vertex is given by $\"%28-b%29%2F2a\"$ , so the equation of the line of symmetry is $\"x=%28-b%29%2F2a\"$ \r
