Determine and state the vertex of f(x) = x² – 2x – 8 using the method of completing the square.

(1,-9)

Step-by-step explanation:

Since the form of a parabola in vertex form is , where h is the x coordinate of the vertex and k is the y coordinate, the vertex of this parabola is at (1,-9). Hope this helps!

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
