    The answer to your question is:

    Step-by-step explanation:

    4y² + x + 8y + 1 = 0

    4y² + 8y = - x - 1

    4 (y² + 8y) = - x - 1

    (y² + 2y) = - 1/4 x - 1/4

    (y² + 2y + 1) = - 1/4 x - 1/4 + 1

    (y² + 2y + 1) = - 1/4 x + 3/4

    (y + 1) ² = - 1/4 (x - 3)

    Vertix (3, - 1)

    It's a parabola that opens to the left.
