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

Back

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

If the vertex of a parabola is at (h, k), what does this tell you about the graph?

Back

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

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

Back

The vertex represents the maximum or minimum value of the function, and it is the point where the graph changes direction.
