2.1 Key Features & Vertex Form of Quadratics

Front

What is the vertex form of a quadratic function?

Front

What does the 'a' value in the vertex form indicate about the parabola?

Back

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

How do you find the vertex of a quadratic function in vertex form?

Front

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

Back

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.

Front

If a quadratic function has a vertex at (4, -1), what is the vertex form of the function if it opens downwards?

Front

What is the effect of changing the 'h' value in the vertex form?

Back

Changing the 'h' value shifts the graph horizontally. If 'h' increases, the graph shifts to the right; if 'h' decreases, it shifts to the left.

Front

What is the effect of changing the 'k' value in the vertex form?

Back

Changing the 'k' value shifts the graph vertically. If 'k' increases, the graph shifts up; if 'k' decreases, it shifts down.

How can you determine if a quadratic function opens upwards or downwards from its equation?
