Question 152551: How do I find the domain of g(t)=log(t+2) and g(x)=ln(x-4): How do I find the domain of g(t)=log(t+2) and g(x)=ln(x-4)

The domain is all x where the function is defined.
The log and natural log functions are only defined when the argument is greater than 0.
For g(t),
t+2>0
t>-2
The domain is t>-2.

For g(x),
x-4>0
x>4
The domain is x>4.
