Question 936101: What is the implied domain of f(x) = 2log(x+3?
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! You cannot take the log of a negative number or 0.
So force the argument/input of the log to be positive
x+3 > 0
x > -3
Therefore, the domain is the set of real numbers x such that x > -3
