As we reflect a function, what happens to its derivative?
Use the checkmarks to trigger a reflection in the function, then observe what happens to its derivative. Use the circles next to the function definitions to toggle their visibility. Repeat this for the cubic, exponential, and sinusoidal functions.

Which of the following best describes how reflections affect the derivative? (Check *all* that apply.)
