Question 246246: find the domain of f(x)=4log8(x2)
and write in interval notations
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! The restriction for logarithms is that you can't have a log of 0, and you can't have a log of a negative number. In other words, x^2>0.
Having said that, x can be any number except x cannot equal zero! In interval notation, this would be
{-inf, 0) U {0, inf).
