Question 1

Which of the following best describes the relationship between the graphs of $$y = e^x$$ and $$y = \ln x as $$shown in the image?

Accepted Answer

They are symmetric with respect to the line $$y = x.$$

Question 2

In the image, which color most likely represents the graph of $$y = e^x$$?

Accepted Answer

The blue curve.

Question 3

Based on the image, what is the domain of the red curve, which represents $$y = \ln x$$?

Accepted Answer

$$(0, \infty)$$

Question 4

Which of the following statements is true about the intersection of the black line and the other two curves in the image?

Question 9

Which of the following best describes the end behavior of the red curve, $$y = \ln x$$, as $$x 	o 0^+$$?

Accepted Answer

$$y 	o -\infty$$

Question 10

If the blue curve is $$y = e^x$$ and the red curve is $$y = \ln x$$, which of the following statements is true?

Accepted Answer
