Pdf transforming the way we teach function transformations.
The last two easy transformations involve flipping functions upside down flipping them around the xaxis, and mirroring them in the yaxis the first, flipping upside down, is found by taking the negative of the original function. Well look at vertical shifts, reflections about the x and y axis, and vertical stretching and shrinking. Reflections are isometric, but do not preserve orientation. In this section, we study how the graphs of functions change, or transform. It is equivalent of picking up the shape and putting it down somewhere else.

Sometimes graphs are translated, or moved about the. To move c spaces to the left, add c to x wherever x appears. When we take a function and tweak its rule so that its graph is moved to another spot on the axis system, yet remains recognizably the same graph, we are said to be translating the function.
