Graphing logarithmic equations

The video tutorial explains how to graph the equation y = 2 Ln(-X) by first graphing the base natural logarithm without transformations, then applying transformations including reflection over the Y axis. The instructor creates a table of values to aid in graphing and discusses the changes in domain and range due to the reflection. The tutorial concludes with a summary of the graphing process and the effects of the transformations.

What transformation is applied to the function y = 2 Ln(-X)?

• Reflection about the X-axis

• Reflection about the Y-axis

• Translation upwards

• Translation downwards

What is the approximate value of the irrational number E used in the graphing process?

• 3.14

• 1.41

• 2.72

• 1.73

What is the X-intercept of the function y = 2 Ln(-X) before reflection?

• (0, 1)

• (1, 0)

• (0, 0)

• (2, 0)

After reflecting the graph over the Y-axis, what is the new domain of the function?

• All positive numbers

• All negative numbers

• All real numbers

• Zero to infinity

Does the asymptote change after reflecting the graph over the Y-axis?

• Yes, it changes to Y = 0

• No, it remains X = 0

• No, it remains Y = 1

• Yes, it changes to X = 1
