    - Use the form a x ^2 + b x + c, to find the values of a, b, and c.

    a = 2, b = - 8, c = 1

    - Consider the vertex form of a parabola.

    a (x + d) ^2 + e

    - Find the value of d using the formula d = b / 2a.

    d=-2

    - Find the value of e using the formula e = c - b ^2 4 a.

    e = - 7

    - Substitute the values of a, d, and e into the vertex form a (x + d) 2 + e.

    2 (x - 2) ^2 - 7
