• If a > 0, the parabola opens upwards. If a < 0, the parabola opens upwards. If ∣a∣ is large (greater than 1), the parabola is wider. If ∣a∣ is small (between 0 and 1), the parabola is narrower.

• If a > 0, the parabola opens upwards. If a < 0, the parabola opens downwards. If ∣a∣ is large (greater than 1), the parabola is narrower. If ∣a∣ is small (between 0 and 1), the parabola is wider.

• If a > 0, the parabola opens downwards. If ∣a∣ is large (greater than 1), the parabola is narrower.

• If a < 0, the parabola opens downwards. If ∣a∣ is large (greater than 1), the parabola is wider.
