Understanding Graph Transformations of Rational Functions

The video tutorial explains how to graph the function g(x) = 1/(x+1) - 2 using the basic rational function f(x) = 1/x. It covers how the values of C and D affect the graph's horizontal and vertical shifts, respectively. The tutorial provides an example of these transformations and demonstrates how to apply them to graph g(x) by shifting key points and asymptotes.

What is the basic rational function discussed in the video?

• f(x) = x + 1

• f(x) = x^2

• f(x) = 1/x

• f(x) = x - 1

In the example, what is the value of C?

• C = 0

• C = -1

• C = 2

• C = 1

In the example, what is the value of D?
