Graphing and describing a vertical translation y = mod(x) - 2

The video tutorial covers graphing and transformations of functions, focusing on understanding parent functions and how transformations affect them. The teacher explains the difference between transformations inside and outside the function and guides students through graphing a transformed absolute value function. The session emphasizes identifying parent functions and applying transformations to graph them accurately.

What is the parent function for the equation Y = |X| - 2?

Describe the transformation represented by the equation Y = |X| - 2.

Explain the difference between transformations that occur inside the function versus outside the function.

What does the transformation on the outside of the function indicate?

How do you graph the function Y = |X| - 2 based on the parent function?
