Best ResponseYou've already chosen the best response.0alright, now substitute (2,0) and (6,0) in the equation.

Best ResponseYou've already chosen the best response.0You don't need the derivative for this. Just plug in your 3 points into x and y to find 3 linear equations with 3 variables (a, b, and c). Then solve this system of equations to get the coefficients of your quadratic.
