First, identify the x and y values in your table, then use them to find the differences. If the second differences are constant, you have a quadratic relation. From there, use systems of equations to solve for coefficients a, b, and c in ax^2 + bx + c.
Ugh, math. Just throw the numbers into an online quadratic regression calculator and let it do the work for you!
I once had to do this in my Algebra course. Find constant second differences, then set up three equations to solve for a, b, and c. It鈥檚 tedious but totally doable!
