You can put this solution on YOUR website! find a quadratic equation whose graph will fit the following points (1,2) (0,5) (-1,14)
----------
Substitute each pair of point values into the form y = ax^2+bx+c.
That will give you three equations in the unknowns a,b,and c.
Solve the system of three equations to find a,b, and c.
Write the formula.
-------------
I get y=3x^2-6x+5
