A transformation takes a figure and manipulates it by moving it in the coordinate plane. There are four types of transformations: reflections, rotations, translations, and dilations. Three of the transformations are called "rigid transformations". This means that the figure will preserve its size when it is transformed.
Identifying transformations. Let's look at four types of transformations: rotations (spinning a shape around a point), translations (shifting a shape), reflections (flipping a shape over a line), and dilations (shrinking or expanding a shape). We practice identifying these transformations in different pairs of figures.

Jul 5, 2024 · Transformations allow us to change any image in a coordinate plane. The transformation is a function, f, that maps to itself, i.e. f: X → X. After the transformation, the pre-image X becomes the picture X. Any or a combination of operations such as translation, rotation, reflection, and dilation can be used in this transformation.
For example, consider the functions g(x) = x2 − 3 and h(x) = x2 + 3. Begin by evaluating for some values of the independent variable x. Figure 2.5.1. Now plot the points and compare the graphs of the functions g and h to the basic graph of f(x) = x2, which is shown using a dashed grey curve below. Figure 2.5.2.

Transformations are movements through space. Consider actions as diverse as: walking and running; the factory machine that makes a thousand music CDs; the opening and closing of an artificial heart valve; the movement of a robotic Mars Rover; strumming a guitar; artistic perspective; and the combined twists and turns of a roller-coaster.
