    Answer: a) The graph opens up.

    Step-by-step explanation:

    The vertex is the minimum/maximum of a parabola.

    We know that the vertex is in the second quadrant (so it is in the quadrant of positive y values and negative x values)

    We also know that it has no real roots, so the graph never touches the x-axis, and knowing that the vertex is above the x-axis, then the graph must open upwards.

    Then the correct option is:

    a) The graph opens up.
