Answer:

Step-by-step explanation:

The vertex form of a parabola

y = a ( x- h)^2 + k        Whre h, k is the vertex  (-1,2) :

                                     y = a ( x - -1)^2 + 2

                                     y = a (x+1)^2 + 2

and includes the point    (0, -1)

           Sub in the point to calculate 'a'

     -1 = a ( 0 +1)^2 + 2

      - 1 = a + 2

               a = -3

So the equation is    y = - 3 ( x+1)^2  + 2

        expands to

                            f(x) =   - 3x^2 - 6x  -1

a = -3     b = -6     c = -1
