Find the union and intersection of these sets: Set T's elements are the integers from -7 to 2; Set R's elements are positive even numbers between 1 and 11.

• Union: {-1, -2, -3, -4, -5, -6, -7, 0, 1, 2, 4, 6, 8, 10} ; Intersection {0, 2}

• Union: {-1, -2, -3, -4, -5, -6, -7, 0, 1, 2, 4, 6, 8, 10} ; Intersection {2}

•    Union: {-7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 4, 6, 8, 10} ; Intersection {0, 2}

•   Union: {-7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 4, 6, 8, 10} ; Intersection {2}
