Math Worksheets

Videos, worksheets, games and activities to help PreCalculus students learn about graph transformations about the x-axis and y-axis or reflective transformations.

Reflect at the x-axis: y = -f(x)

Reflect at the y-axis: y = f(-x)

Graph Transformations about the x-axis and y-axis

This videos discusses reflections around the x-axis and y-axis.

There are different types of transformations and their graphs, one of which is a math reflection across the y-axis. If we get the same function from a math reflection, it is a symmetrical function, specifically even. A math reflection flips a graph over the y-axis, and is of the form y = f(-x). Other important transformations include vertical shifts, horizontal shifts and horizontal compression. This video explains how to graph reflections across the x-axis and y-axis in the form a×f(b(x-c))+d. This video looks at how the sign of a and b affect the graph of f(x).
