Question 93237
find the domain of the following: I need help I am so lost 
f(t)=4.5e^t
t can take on any value; domain is "all Real Numbers"
-----------------
g(x)=log(x+3)
x+3 cannot negative; domain is "all Real Numbers greater than or equal to -3"
------------------
g(x)=2^x
x can take on any value; domain is "all Real Numbers"
---------------
g(t)-ln(t-1) 
t-1 cannot be negative; domain is "all Real Numbers greater than or equal to 1"
--------------------
