Vertex Form Quadratics

What is the vertex form of a quadratic equation?

Front

How does the value of 'a' affect the graph of a quadratic in vertex form?

Back

The value of 'a' determines the direction and width of the parabola. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards. A larger absolute value of 'a' results in a narrower parabola.

What does the vertex of a parabola represent?

Back

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

What is the effect of a negative 'a' value in vertex form?

Back

A negative 'a' value reflects the parabola over the x-axis.

If a parabola opens upwards, what can be said about its vertex?

Back

If a parabola opens upwards, its vertex is the minimum point on the graph.
