If the universal set is U = { 1, 2, …, 9, 10 } andA= { 1, 4, 7, 10 } andB= { 1, 2,3, 4, 5 } and C= { 2, 4, 6, 8 } then which of the following represents the setU\(AB)?A: { 1, 4, 6, 8, 9 }3. If A, B, and C are any sets, then is the following statement true or false?(AB)C=A∩ (BC)A: False4. If the universal set is U = { 1, 2, …, 9, 10 } andA= { 1, 4, 7, 10 } andB= { 1, 2,3, 4, 5 } andC= { 2, 4, 6, 8 } then which of the following represents the setB(A\C)?A: { 7, 10 }5.IfA= {xN|x< 7 },B= {xZ| |x5 | < 3 }, and C = { 2, 3 } then whichof the following list of elements represents the set (AB)\C?A: {1, 7 }6. Given the statement, which of the following is the negation?Either x is a negative number or x is not greater than 3.A:Either x is not a negative number and x is greater than 3

Define a function f from Z to Z by f(n) = (n1)*(1n).What is the value of f(4)?A:-259. Define a function f from Z to Z by f(n) = (n1)*(1n).What is the value of f(3.5)?A:undefined10. If a1= 5 and ak + 1= 3akfor k > 0 then a4= 135A: True11. Given the following relation on sets A and B defined below, select the correctanswer.A = { 1, 2, 3, 4, 5 }B = { a, b, c, d, e }The relation R = { (1, a), (3, b), (5, c), (4, d), (2, e) }A: Is a function that is bijective12. Define a function f from the product Z × Z to Z by f(a, b) = ab.Is the function 1 to 1?A: False13. Given the following relation on sets A and B defined below, select the correctanswer.A = { a, b, c, d, e }B = { 1, 2, 3, 4, 5 }The relation R = { (a, 2), (b, 1), (c, 3), (d, 5) }A: Is Not a Function
