To reflect about the x-axis, multiply f(x) by -1 to get -f(x). To reflect about the y-axis, multiply every x by -1 to get -x.

The rule for a reflection in the origin is Step 3 : The graph y -x can be obtained by reflecting the graph of y x across the y-axis using the rule given below. Step 2 : So, the formula that gives the requested transformation is. Some simple reflections can be performed easily in the coordinate plane using the general rules below. Step 1 : Since we do reflection transformation across the y-axis, we have to replace x by -x in the given function. Another transformation that can be applied to a function is a reflection over the x x or y y -axis. Therefore, to graph h(x), we simply reflect g(x) over the y-axis by finding a few points on g(x), multiplying the x-coordinate by -1, and plotting the new points. Determine whether a function is even, odd, or neither from its graph. The fixed line is called the line of reflection. Learning Outcomes Graph functions using reflections about the x x -axis and the y y -axis. When reflecting a figure in a line or in a point, the image is congruent to the preimage.Ī reflection maps every point of a figure to an image across a fixed line. The above odd function is equivalent to: f(x) x(x + 3) (x 3) Note if we reflect the graph in the x -axis, then the y -axis, we get the same graph. An example of an odd function is f(x) x 3 9x. An odd function either passes through the origin (0, 0) or is reflected through the origin. Figures may be reflected in a point, a line, or a plane. This kind of symmetry is called origin symmetry.
