The document describes various transformations that can be applied to a graph y=f(x) to generate other graphs. These transformations include: shifting the graph up or down by adding or subtracting a constant a; stretching or compressing the graph vertically by multiplying y by a constant k; reflecting parts or all of the graph across the x-axis or y-axis; and stretching or compressing the graph horizontally by multiplying x by a constant k. Combinations of these transformations can be used to transform the original graph in various ways.
