What does the coefficient 'a' indicate in the quadratic equation?

Back

The coefficient 'a' indicates the direction of the parabola's opening. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

What does it mean if a parabola opens downwards?

Back

If a parabola opens downwards, it means that the coefficient 'a' in the quadratic equation is negative.

Front

How can you determine the direction a parabola opens by looking at its equation?

Back

The direction of the parabola can be determined by the sign of 'a': if 'a' is positive, it opens upwards; if 'a' is negative, it opens downwards.
