Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Check all of the boxes that apply.

1.) The vertex is (1, -9).
2.) The graph opens upward.
3.) The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.
4.) The graph is steeper than the graph of f(x) = x2.
5.) The graph is the same as the graph of f(x) = 6×2 + 12x – 3.
