Graph piecewise functions logarithmic and reciprocal

The video tutorial covers the concept of piecewise functions, focusing on graphing two specific functions: the reciprocal function and the natural logarithm function. The instructor explains how to apply domain restrictions and transformations to these functions. The tutorial highlights the importance of understanding basic graphs and transformations, and it discusses the types of discontinuities present in the graphs, particularly focusing on vertical asymptotes.

What is a piecewise function and how is it represented on a coordinate grid?

Explain the process of graphing the function Y = -1/X and the transformations applied.

What are the domain restrictions for the function Y = -1/X and how do they affect the graph?

Describe the characteristics of the natural logarithm function and its graph.

What is the significance of the vertical asymptote at X = 0 for both parent functions discussed?
