Understanding Graph Transformations

The video tutorial explains the graph of the function f(x) = 1/x and its transformations. It covers horizontal and vertical shifts, reflections across the x-axis, and vertical stretches. Each transformation is matched with a corresponding graph, demonstrating how the function changes. The tutorial concludes with a review of basic transformations, including reflections, shifts, and stretches.

What is the basic function discussed in the video?

• f(x) = x + 1

• f(x) = x^2

• f(x) = 1/x

• f(x) = x - 1
