Question 911615: I need to know the vertex, axis of symmetry, roots, domain, range for the following problem
Y=2(x+1)^2-4
i also need to know if it opens up or down and if you can graph it that would be greatly appreciated.

Need to Know: the vertex form of a Parabola opening up(a>0) or down(a<0):
where(h,k) is the vertex and x = h is the Line of Symmetry
Y= (x+1)^2-4
Upward a = 2 > 0
V(-1,-4), axis of symmetry: x = -1
