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.

In vertex form, f(x) = 6(x + 1)² − 9 has vertex (−1, −9), and the positive coefficient 6 means the parabola opens upward. Since |6| > 1, it is narrower than y = x². Expanding gives 6(x² + 2x + 1) − 9 = 6x² + 12x − 3, so the equivalent equation is the one in choice E.
