Exploring Reflections in Function Transformations

This video tutorial covers function transformations, focusing on reflections across the X and Y axes. It explains how changing the signs of 'A' and 'B' in function equations affects graph reflections. The tutorial uses T tables for comparison and provides visual animations to illustrate these transformations. Examples include square root and cubed root functions, demonstrating how to graph these transformations. The video concludes with a preview of upcoming topics on combined transformations.

What does changing the sign of 'A' in a function do to its graph?

• Reflects it across the y-axis

• Compresses it horizontally

• Reflects it across the x-axis

• Stretches it vertically

If y = f(-x), what transformation occurs to the graph of f(x)?

• Reflection across the x-axis

• Vertical stretch

• Reflection across the y-axis

• Horizontal compression
