What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the graph of a quadratic function, represented as (h, k) in the vertex form of the equation y = a(x - h)² + k.

What does it mean if the vertex of a quadratic function is at its minimum?

Back

It means that the parabola opens upwards, and the vertex represents the lowest point on the graph.

What are the coordinates of the vertex of the function y = 2x² - 4x + 1?

Back

The vertex is at (1, -1).

Front

How do you determine if a vertex is a maximum or minimum?

Back

If the parabola opens upwards, the vertex is a minimum. If it opens downwards, the vertex is a maximum.

Front

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

Back

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