SOLUTION: Find the domain of the function f(x) = ln(12x

SOLUTION: Find the domain of the function f(x) = ln(12x - 48)

Question 114118: Find the domain of the function f(x) = ln(12x - 48)
Answer by Edwin McCravy(20065) (Show Source): You can put this solution on YOUR website!

We can only take natural logs of positive numbers.  So we set 'what the
natural log is taken of' greater than 0.

12x - 48 > 0
     12x > 48
       x > 4
