Question 1. Find the domain and range of these functions. Note that in each case, to find the
domain, determine the set of elements assigned values by the function.
a. the function that computes the parity of the last bit of a string
b. the function that divides a real value by a if it is an irrational number, or multiplies it by
Tt if it is a rational number
c. the function that takes two integer numbers and computes the resulting simplified
fraction (assume the first one is the numerator and the last one the numerator)
d. the function that takes a rational number greater than zero and computes an ordered
pair with the numerator and the denominator as its elements
