Instructions Let A, B, C, D, E, and F be sets, where: A is the set of natural numbers smaller than 10: B is the set of even integers greater than 0 but smaller than 10; . C = {0}; D={-1,1,4}; . E is the set of natural numbers smaller than 4; and . F is the set of integers larger than 4. Complete the following problems by filling in the blanks or, where indicated, by providing a labeling, Blanks permit single characters (e.g., '2') or complex characters representing arithmetic operations (e.g.. .-2.9", V2",291'), but not strings (e.g.."{0}" is a string comprised of the characters {}, "0", and "'). When finished, upload the PDF file produced from compilation of your LaTex file) to Blackboard. Problem 18. In set builder notation, C = {2: Problem 19. In set builder notation, F = { : Y Problem 20. In set builder notation, N= { ___Z:____}. Relationships Now let A, B, C, D, E, and F be sets, where: A={-1,2,3); B = {1,4,6,9}; . C = {1,3}; D = {1,4}; E = {1,9}; and F = {x Z:r> 1 and 2
