What is a transformation in mathematics?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

Front

What does it mean to reflect a graph?

Back

To reflect a graph means to flip it over a specific line, such as the x-axis or y-axis, creating a mirror image.

Front

What is a stretch transformation?

Back

A stretch transformation enlarges or shrinks a graph vertically or horizontally, affecting the distance between points on the graph.

Front

What is a shrink transformation?

Back

A shrink transformation reduces the size of a graph vertically or horizontally, making it closer to the axis.

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

Back

Front

Back

The vertex is (4, 1).

Front

Back

a = 1, h = -3, k = 2.

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, given by the equation x = h.

Front

Back

The axis of symmetry is x = 3.

Front

What is a parabola?

Back

A parabola is the U-shaped graph of a quadratic function, which can open upwards or downwards.
