Question

1) Dados os intervalos A= [1,4], B= [0,3] e C= [2,5], determinar: a) A - B b) A - C c) B - A d) B - C e) C - A f) C - B

Answer 1

Resposta:

A = [ 1 , 4 ]

B = [ 0, 3 ]

C = [ 2, 5 ]

a) A - B

x = 1 - 0

x = 1

y = 4 - 3

y = 1

A - B = [ 1, 1 ]

b) A - C

x = 1 - 2

x = - 1

y = 4 - 5

y = - 1

A - B = [ -1, -1 ]

c) B - A

x = 0 - 1

x = - 1

y = 3 - 4

y = - 1

B - A = [ -1, - 1 ]

d) B - C

x = 0 - 2

x = -2

y = 3 - 5

y = -2

A - B = [ -2, -2 ]

e) C - A

x = 2 - 1

x = 1

y = 5 - 4

y = 1

C - A = [ 1, 1 ]

f) C - B

x = 2 - 0

x = 0

y = 5 - 3

y = 2

C - B = [ 0, 3 ]
