Problem 3 Let X be the set of names of the integers from zero to nine, so that X = {zero, one, two, ..., nine}. Let R be the relation such that two names x and y are related if they have the same number of letters.
a) Describe R using any two of the following four methods: • as a set with an explicit list of elements as a set described with set builder notation • as a diagram with dots and arrows • as a shaded region in a cartesian-type plane b) Prove that R is an equivalence relation. c) Describe the equivalence classes of R and the corresponding partition of X. d) Prove or disprove that R is a function from X to X.
