Vertex Form Quadratics

Front

What is the vertex of the quadratic function f(x)=4(x-2)² + 3?

Back

(2, 3)

Front

What is the green dashed line in a parabola called?

Back

Axis of symmetry

Front

If a parabola has a vertex at (-3,2), where is the axis of symmetry?

Back

x = -3

Front

Does the parabola f(x)=4(x-2)² + 3 open up or down?

Back

Opens up

Front

Identify the vertex and whether the graph opens up or down for the function f(x) = 4(x + 5)² + 2.

Back

(-5, 2); opens up

Front

What is the general form of a quadratic function?

Back

f(x) = ax² + bx + c

Front

What does the 'a' value in vertex form f(x) = a(x-h)² + k indicate about the parabola?

Back

It indicates the direction the parabola opens (up if a > 0, down if a < 0).

Front

What is the vertex form of a quadratic function?

Back

f(x) = a(x-h)² + k, where (h, k) is the vertex.

Front

How do you find the axis of symmetry from the vertex form?

Back

The axis of symmetry is x = h, where (h, k) is the vertex.

Front

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

Back

It shifts the parabola left or right.
