Question 160776: I'm not sure if this is the right location to ask these questions. I only have 2 out of 52 questions left in my book and was wondering if anyone could help. First question asks Name all the subsets of the given universal set. U={0,2,4}. I only get (0)(2)(4)(2,4)(0,2)(0,4). the book asks for 2 more .What am I missing. Second question asks. Find the solution set of each open sentence from the given domain. 2x=8; D={Intergers}. I have done 4 of these already can't seem to figure this one out. can anyone please help me finish this book. Thanks.
