Question

if A= { X:X € z and -2 <_ x<2} and b = { x:x € Z and x2=4} find A-B and write in set builder form​

Answer 1

Step-by-step explanation:

Given:-

A= { X:X € z and -2 <_ x<2} and B = { x:x € Z and x2=4}.

To find:-

find A-B and write in set builder form

Solution:-

Given sets are :

A= { X:X € z and -2 ≤x<2}

A={-2, -1, 0, 1 }

B = { x:x € Z and x²=4}.

B={-2, 2}

A-B={-2, -1, 0, 1} - {-2 ,2}

A-B={-1, 0 ,1}

A-B={X:X€Z and -1 ≤ X ≤ 1} (or)

A-B={X:X€Z and -1 ≤ X < 2}

Answer:-

A-B={-1, 0 ,1}

A-B={X:X€Z and -1 ≤ X ≤ 1} (or)

A-B={X:X€Z and -1 ≤ X < 2}
