How do you graph the following logs?
f(x)=log5 (x2)
f(x)=log5 x2
f(x)= log5 x
f(x)=log5 (x+2)

Reiny,
use f(x)= log_{5} x as your reference graph.
You should know what your standard log function graph looks like
If you translate the reference graph 2 units to the right, you get the first equation
If you translate the reference graph 2 units to the left, you get the last equation
If you translate the reference graph 2 units downwards, you get the second equation
