    set up the general quadratic equation (for a parabola) as: y=ax^2+bx+c use 3 of the 4 sets of known points (x,y) to obtain a system of 3 equations, solve for a, b and c. Example: 10=a(0.5)^2+b(0.5)+c 10.5=a(0.75^2+b(0.75)+c 9=a+b+c Solving for a, b and c gives a=-16, b=22, =3 I will leave the factoring to you.
