(A)
domain:
{ element : } (all non-negative real numbers)
(B).
the numerator is which means can be or any positive number because if is negative number we will have complex solution
denominator cannot be equal to zero; so, find values that make it equal to zero and exclude them from set of solutions
=> =>
domain is:
{ element : or }
(assuming a function from reals to reals)
