Question 139254
Find the domain of the logarithmic function
f(x) =In (1-x) 
:
The thing to remember is that we can't have a log of a negative number;
Also we can't have a log of 0
Therefore there won't be any values of x >= 1
:
Remember you can have negative values for x; for example ln(1 - (-10)) is ln(1+10)
:
Therefore the domain will be all real numbers < 1
