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

  1. This is false - the vertex is (-1, -9).
  2. This is true - the coefficient of x² is positive, meaning that the graph opens upward.
  3. This is false - the graph is obtained by shifting down 9 units.
  4. This is true - the coefficient of x² is greater for f(x)=6(x+1)² - 9 compared to f(x) = x².
  5. This is true - upon expanding, we get f(x) = 6x² + 12x -3.
