Question

Represent the following sets in Roster form. (i) A = The set of all even natural numbers less than 20. (iv) D = { x : x ∈ Z, -5 < x≤ 21}​

Answer 1

Answer:

i) A = The set of all even natural numbers less than 20.

A = { 2 ,4,6,8,10,12,14,16,18,} ans

= A = {x:x is even natural number x > 20} ans

iv) D = {x : x ! Z, –5 < x ≤ 2}

= D =  {-4,-3,-2,-1,0,1,2}
