what is the domain of the function y = 3 ln x graphed below?\n○ x>0\n○ x<0\n○ x<3\n○ x>3
Answer
Explanation:
Step1: Recall domain of natural - log function
The domain of the natural - logarithm function $y = \ln x$ is $x>0$. The function $y = 3\ln x$ is a vertical stretch of $y=\ln x$ by a factor of 3, which does not change the domain.
Answer:
A. $x > 0$
