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 depending on the sign of the coefficient 'a'.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on whether it opens downwards or upwards.

Front

What is the range of a quadratic function that opens upwards?

Back

The range is all real numbers greater than or equal to the y-coordinate of the vertex.

Front

What is the range of a quadratic function that opens downwards?

Back

The range is all real numbers less than or equal to the y-coordinate of the vertex.

Front

What does it mean for a quadratic to have a maximum value?

Back

A quadratic has a maximum value if it opens downwards, meaning the vertex is the highest point on the graph.

Front

What does it mean for a quadratic to have a minimum value?

Back

A quadratic has a minimum value if it opens upwards, meaning the vertex is the lowest point on the graph.
