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
