Question

find equation of parabola : y = ax^2 + bx + c
using given points : (-5, 6) (2, 20) (1, 0)

Answer 1

It looks like we'll need to define a system of equations in order to solve this.
If we substitute each point into the formula, we'd get three equations of a, b, and c. Then, we can solve the system to find the a, b, and c.
