    f (x) = (x - 3) ² - 1

    Step-by-step explanation:

    The equation of a parabola in vertex form is

    y = a (x - h) ² + k

    where (h, k) are the coordinates of the vertex and a is a multiplier

    To obtain this form use the method of completing the square

    Add/subtract (half the coefficient of the x - term) ² to x² - 6x

    f (x) = x² + 2 ( - 3) x + 9 - 9 + 8

    = (x - 3) ² - 1
