What is the equation of a parabola with the points (4,-6) and (6,-6)?

Answer 1

Three points are required to define a parabola. As both 4 and 6 have values of 6, the general form of the parabola is c(x-4)(x-6) - 6. You can expand this if you wish and get cx^2 - 10cx + 24c - 6

c is not equal to 0 to get a parabola.
