WebA function can be reflected over the x -axis when we have – f ( x) and it can be reflected over the y -axis when we have f (- x ). Here, we will learn how to obtain a reflection of a function, both over the x -axis and over the y -axis. We will use examples to illustrate important ideas. WebExample 1. Fig. 1 is the graph of this parabola: f ( x) = x2 − 2 x − 3 = ( x + 1) ( x − 3). The roots −1, 3 are the x -intercepts. Fig. 2 is its reflection about the x-axis. Every point that was above the x -axis gets reflected to below the x -axis. And every point below the x -axis gets reflected above the x -axis.
Web1 2 Reflections of graphs Graphs can be reflected in either the \ (x\) or \ (y\) axes. Reflections in the x-axis If \ (f (x) = x^2\), then \ (-f (x) = - (x^2)\).... WebPutting a "minus" on the argument reflects the graph in the y -axis. Putting a "minus" on the whole function reflects the graph in the x -axis. So my (clearly labelled) answer is: reflection in the y -axis: f (− x) = x2 − x − 3 reflection in the x -axis: − f ( x) = − x2 − x + 3 Many textbooks don't get any further than this.
Web12. sep 2014 · Adding to @Adriano's answer, if you want to reflect y = f ( x) across y = m x + b you have to reflect the function by the x-axis and then rotate it by θ = π + 2 tan − 1 ( m) radians. So if we have y = f ( − x), then by using the rotation matrix in linear algebra, we can set x = x ′ cos ( θ) + y ′ sin ( θ) and y = y ′ cos ( θ) − x ′ sin ( θ).
