Front

What does the 'a' value indicate in the vertex form?

Back

The 'a' value indicates the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.

Front

How can you find the vertex from a graph?

Back

The vertex can be found at the highest or lowest point of the parabola on the graph.

What is the axis of symmetry in a quadratic function?

Front

How do you determine the direction of a parabola from its equation?

Back

The direction of the parabola is determined by the sign of 'a' in the vertex form: positive for upwards, negative for downwards.

Front

What is the effect of changing the 'k' value in the vertex form?

Back

Changing the 'k' value shifts the graph vertically: increasing 'k' moves the graph up, while decreasing 'k' moves it down.

Front

What happens when 'h' is increased in the vertex form?

Back

Increasing 'h' shifts the graph horizontally to the right, while decreasing 'h' shifts it to the left.
