Front

Define the vertex of a quadratic function.

Back

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

Front

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

Back

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