Question

question 4 of 10
this could be the graph of:
a. $ln(x + 3)$
b. $ln(x - 3)+4$
c. $ln(x + 3)-4$
d. $ln(x)+4$

Explanation:

Step1: Recall properties of logarithmic functions

The general form of a logarithmic function is $y = a\ln(b(x - h))+k$, where $(h,k)$ is the horizontal and vertical shift. The vertical - asymptote of $y=\ln(x)$ is $x = 0$.

Step2: Identify the vertical asymptote of the given graph

The vertical asymptote of the given graph is $x = 3$. For a function of the form $y=\ln(x - h)+k$, the vertical asymptote is $x=h$. So $h = 3$.

Step3: Identify the vertical shift

The graph seems to be shifted up by 4 units compared to the basic $\ln(x)$ function. In the form $y=\ln(x - h)+k$, when $k>0$, the graph is shifted up by $k$ units. Here $k = 4$.

Answer:

B. $\ln(x - 3)+4$
