What are the zeros of a quadratic function?

Back

The zeros of a quadratic function are the x-values where the function equals zero, also known as the roots or x-intercepts.

Front

What does it mean if a parabola opens upwards?

Back

If a parabola opens upwards, it has a minimum value at its vertex, and the coefficient 'a' in the quadratic equation is positive.

Front

What does it mean if a parabola opens downwards?

Back

If a parabola opens downwards, it has a maximum value at its vertex, and the coefficient 'a' in the quadratic equation is negative.

Front

How can you determine if a quadratic function has a maximum or minimum value?

Back

You can determine this by looking at the sign of the coefficient 'a': if 'a' is positive, it has a minimum; if 'a' is negative, it has a maximum.
