# Finding Domains of Functions: Example Problems

Find the domain of the following:

1) g(x)=5^x

Explain how you obtained your answer.

2) g(x)=1n(x-4)

Show your work or explain how you obtained your answer.

3) g(t)=log(t+2)

Explain how you obtained your answer.

4) f(t)=5.5e^t

Show your work or explain how you obtained your answer.

...ill be the set of all real numbers. Domain is : R

2) g(x)=ln(x-4),

In this one, the allowed values for the given function are restricted by the fact that the log of 0 and negative numbers is not defined. So, that gives us x-4 > ...
