Answer 1

Respuesta:

A = [-3, 10) = {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

B = (-1, 12] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

A' = {-9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3}

B' = {-12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0}

a. {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

b. {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

c. {-3, -2, -1}

d. {10, 11, 12}

e. {1, 2, 3}

f. {-12, -11, -10}
