We can reflect the graph of y=f (x) over the x-axis by graphing y=-f (x) and over the y-axis by graphing y=f (-x). See this in action and understand why it happens.

Connect the graphical and algebraic presentations of function reflection across the x-axis and across the y-axis.

The point A has coordinates (6, 0) . What point do we get when we reflect A across the y -axis and then across the x -axis?

We can plot points after reflecting them across a line, like the x-axis or y-axis. Reflections create mirror images of points, keeping the same distance from the line. When we reflect across the y …

Now, if we want to stay on this line to find the reflection, we just do the same thing. We could decrease X by four, so we'll go from negative two to negative six, and decrease Y by four, and …

Sal says near the end of the video that the negative flips it over the y-axis, is it also correct to say that it is reflected over the x-axis.

Given a shape and its image under a horizontal or vertical reflection, determine the line of reflection.

We essentially take the terminal ray of the angle and we reflect it about the X or the Y axis, or both axes. What I want to do in this video is think a little bit about the tangent of these different …
