WebIn addition to shifting, compressing, and stretching a graph, we can also reflect it about the x -axis or the y -axis. When we multiply the parent function f (x) = bx f ( x) = b x by –1, we get a reflection about the x -axis. When we multiply the input by –1, we get a reflection about the y -axis. For example, if we begin by graphing the ...
