The domain of a function f is the largest subset of R at which f can be defined. write the domain of the following function in interval notation i.e using
[,(,),] , U n , \
I know for the first one, in order for it to be defined in the set of reals, it cannot be negative, so i have to exclude all numbers that are going to make that function negative, but i dont know how to write this in 'interval notation'
and no idea how to go about the second one, any help appreciated
