The video tutorial explores the concept of function reflection using the Desmos graphing calculator. It demonstrates how to reflect functions over the x-axis, y-axis, and both axes using simple and complex functions. The tutorial explains the mathematical reasoning behind these transformations and encourages viewers to experiment with Desmos to build intuition.

What is the primary tool used in this tutorial for graphing functions?

• WolframAlpha

• GraphCalc

Why does placing a negative sign in front of a function reflect it over the x-axis?

• It changes the sign of the x-values

• It shifts the graph horizontally

• It changes the sign of the y-values

• It shifts the graph vertically
