Identify transformations, domain and limits of a reciprocal function

The video tutorial covers graph transformations, including reflection over the X axis, vertical stretching, and shifting. It explains how to identify variables and transformations, and how to determine the domain and limits of a function using number lines and inequalities. The tutorial emphasizes understanding the impact of these transformations on the graph's appearance and behavior.

Explain the significance of the domain in relation to the denominator of a function.

What does the limit as X approaches negative infinity from the left indicate?
