Step-by-step explanation:
We want to graph:
[tex]f(x) =\log_{5}(x - 3) [/tex]
We first graph the parent function
[tex]g(x) =\log_{5}(x) [/tex]
This parent function has x-intercept at (1,0) and it is asymptotic to the y-axis.
We then shift the graph of the parent function 3 units right, to obtain the graph of
[tex]f(x) =\log_{5}(x - 3) [/tex]
The new x-intercept will be (4,0) and vertical asymptote will now be x=3.
