domain of 2^(x+1)

-------------------------------------------------------------------------

Domain is the values of x for which the function is defined.

$y=2^{x+1}$

$y=2^{x}+1$

In the case of both these functions we can see that for any real value of x the function is defined(i.e. a y value exists).

So the domain is all real numbers.

ANSWER: Domain = all real numbers
