# Decide among the following sets, which are subsets of which:

A = {x:x satisfies x^{2} – 8x + 12=0}

B= {2,4,6}

C= {2,4,6,8,….}

D={6}

Answer :

A = x^{2} – 8x + 12=0

= (x–6)(x–2) =0

= x=2 or x=6

A = {2,6}

B ={2,4,6}

C= {2,4,6,8}

D ={6}

So we can say

D⊂A⊂B⊂C

Rate this question :

Write each of the following intervals in the set-builder from:

(i) A = (–2, 3)

(ii) B = [4, 10]

(iii) C = [–1, 8)

(iv) D = (4, 9]

(v) E = [–10, 0)

(vi) F = (0, 5]
