Front

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

Back

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

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its direction.

How do you find the axis of symmetry for a quadratic equation?

Front

What is the minimum value of a quadratic function?

Back

The minimum value occurs at the vertex if the parabola opens upwards.

Front

What is the maximum value of a quadratic function?

Back

The maximum value occurs at the vertex if the parabola opens downwards.

Front

What is the y-intercept in a quadratic equation?

Back

Front

What are the zeroes of a quadratic function?

Back

The zeroes (or roots) are the values of 'x' where the quadratic equation equals zero.

Front

How can you determine the direction of a parabola?

Back

The direction of a parabola is determined by the sign of the coefficient 'a'. If 'a' > 0, it opens upwards; if 'a' < 0, it opens downwards.
