Question

(0,7) (1,5) (-1,13)

How to find the quadratic equation given only these points (standard form)

Answer 1

(x - 1)^2 =1/2 ( y - 5) or 2x^2 - 4x - y + 7 = 0

Explanation:

(x - 1)^2 =1/2 ( y - 5)

or

x^2 - 2x + 1 = y/2 - 5/2

2x^2 - 4x + 2 - y + 5 = 0

2x^2 - 4x - y + 7 = 0

Summit (1,5) = (h,k)

4p = 2

p = 1/2

(x - h)^2 = 1/2(y - k)
