Question 319986: Give an example of a quadratic equation in standard form that passes through the points (0, -14), (7, -28) and (5, -4). None of the given points is the vertex.
I am so lost! I plugged the values of x and y into the standard form, but I don't know what to do from there!

You can put this solution on YOUR website!
plugging the 3 points into the standard equation (y = ax^2 + bx + c) gives you 3 equations and 3 unknowns (a , b , and c)

solve the system of equations to find the unknown coefficients
