Remember when we were graphing exponentials and logs.......
Use this information along with what we know about
transforming graphs to find the domain and range of
logarithmic functions
Find the Domain, Range and vertical asymptotes of the function
A) f(x) = log(x + 5)

B) f(x) = -4log x
C) f(x) = 2 - log(x + 1)
