How do you find the domain of #f(x)=e^x - 6#?
The domain of a function is essentially asking what are the "legal" values of
Illegal values are values that would make you divide by zero, or would result in negatives under square roots. In this function, there are no values that would make you divide by zero. There are also no roots, so there is no risk of getting a negative value under a root.
So there are no "illegal" values of
