Question

Write the given set from roster form to set-builder form $A=\left\{5,6,7,8,9,10.\right\}$

Answer 1

Set-builder form-

When the elements of the set are not listed but described by a property possessed by all the elements of the set. The numbers in the given set are natural numbers from$4to11$. So in set-builder from $A=\{x:x\in Nand4<x<11\}$.

Hence, set-builder form is $A=\{x:x\in Nand4<x<11\}$
