domain to R or not. Circle the appropriate answer. (3 points /
part) a) f(x) = 1 / (x2 - 13), x ∈ R. Yes No b) f(x) = √x2 − 13, x
∈ R. Yes No c) f(A) = the largest element of A, where A ∈ P({1, 2,
3}), the power set of {1, 2, 3}. Yes No In the following S denotes
the set of all bit strings of length n ≥ 1. d) f(s) is the position
of a 0 bit or 1 bit in s where s ∈ S. Yes No e) f(s) is the number
of 0 bits divided by number of 1 bits in s where s ∈ S. Yes No
