Question

Here is the graph of a quadratic function f.

Answer 1

B) x² - 8x + 12

E) (x -4)² - 4

F) (x - 2)(x - 6)

Step-by-step explanation:

As the graph opens upwards. The value of x² will be positive.

The x intercepts are (2, 0), (6, 0) determining (x -2)(x-6)

The (x - 4)² - 4 determines the vertex of x = 4, y = -4

When simplified:

⇒ (x -2)(x-6)

⇒ x² - 2x -6x + 12

⇒ x² - 8x + 12
