How can i demonstrate that two paraboles are simmetrycal to eachother through a point?

For example.. one way would be to trace a line through that exact point(take it M) and then find out the coordinates of the points the line intersects with the paraboles(S1 and S2 for Parabole 1 & T1 and T2 for Parabole 2). Then demonstrate that M is also the middle of segment S1T1 (or other possible combinations). Any other suggestions?

Graph them! The symmetry will be visually obvious.
The page below will make graphs for you such as the parabolas
x^2-2x+1
3x^2+2x+2

I wish to help u but i cant remember them. And i dont know how i passed them. The only thing i remember about paraboles problem: 'The paraboles are problem'.

You could try using Calculus. Finding the formula for the tangent line through point "M." Sorry, that's all I got.
