ANSWER ::

A - B = { -3,-2 }

B - A = { 0, 2 }

Answer 2

Answer:

A - B = {-3,-2}

B - A = {0,2}

Step-by-step explanation:

Given,

A = { -3,-2, 1 , 4}

B= { 0, 1, 2,4, }

To find,

A- B and B-A

Recall the concept

If A and B are any two sets, then the difference of the sets A - B is defined as the set of all elements that are present in set A, but not in B

Similarly, the B-A is defined as the set of all elements that are present in the set B but not in A

Solution:

We have A =  { -3,-2, 1 , 4}

B = { 0, 1, 2,4, }

The elements that belong to set A, but not in set B are -3,-2,

A - B = {-3,-2}

The elements that belong to the set B, but not in set A are 0,2

B - A = {0,2}

∴A - B = {-3,-2}

B - A = {0,2}
