Equation(s):

Title : Jan 31-7:08 PM (Page 7 of 11)

Equation in vertex form:

The vertex is (-1, -2) so h = -1 and k = -2

To find a , substitute any point except the vertex

Sub (1, 0):

The equation in vertex form is

Title : Jan 31-7:08 PM (Page 8 of 11)

Equation in factored form:

where s and t are the zeroes,or roots, of the parabola

s = -3 and t = 1

To find a , substitute any point except one of the zeroes - the vertex is (-1, -2)

The equation in factoredform is
