This video tutorial covers transformations on reciprocal functions, starting with an introduction to the parent function f(x) = 1/x. It explains how to analyze graphs for vertical and horizontal asymptotes and describes the effects of transformations such as horizontal and vertical shifts, reflections, and stretches. The tutorial concludes with examples to illustrate these transformations.

What is the parent function of a reciprocal function?

• f(x) = 1/x^2

• f(x) = x^2

• f(x) = 1/x

• f(x) = x
