Factor this trinomial: 2x² + 11x + 12

• (x + 3)(2x + 4)

• (2x + 2)(x + 6)

The graph of f(x) = x² has been transformed so that the vertex is now (-2, 8), it opens upward, and is now 3 times as steep. What is the new equation?

• f(x) = (x - 2)² - 8

• f(x) = 3(x + 2)² + 8

• f(x) = -3(x + 2)² + 8

• f(x) = 3(x + 2)² - 8
