Front

What does the graph of a quadratic function look like?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards.

Front

What determines the direction in which a parabola opens?

Back

The direction of a parabola is determined by the coefficient 'a' in the quadratic function. If 'a' is positive, it opens upwards; if 'a' is negative, it opens downwards.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on the direction it opens.

Front

What are the roots of a quadratic equation?

Back

The roots of a quadratic equation are the values of x for which the quadratic function equals zero, also known as the x-intercepts.

Front

What is the maximum or minimum value of a quadratic function?

Back

The maximum or minimum value of a quadratic function occurs at the vertex. If the parabola opens upwards, it has a minimum value; if it opens downwards, it has a maximum value.
