Front

What does the vertex of a parabola represent?

Back

The highest or lowest point of the parabola.

Front

What is the formula to find the y-coordinate of the vertex?

What is the significance of the coefficient 'a' in a quadratic function?

Back

It determines the direction of the parabola (upward if a > 0, downward if a < 0).
