I need a breakdown for my son's homework

thanks!

try to find a,b,c in terms of $\displaystyle y_0,y_1$ and $\displaystyle y_2$

3. ## Re: Mathmom's Contest

Yes, that is what I cannot figure out how to accomplish

4. ## Re: Mathmom's Contest

here's a clue

you know that $\displaystyle (-h,y_0),(0,y_1),(h,y_2)$ satisfies the equation. So you can substitute those points to the equation and get three equations with a,b,c and $\displaystyle y_0,y_1,y_2$. There you go.

Look, admittedly I'm not a mathematician. I'm a single mother of two boys, and I cant work through this, nor can my son recall ever seeing it in class. We need it clearly worked out

Then your son should go to his teacher and ask about this problem. If he has been given a problem like this, he is clearly expected to be able to understand it even if not complete it. The last thing you want to do is trick his teacher into thinking he can do it so he doesn't need more instruction!
