thanks !

Art now a days. For it she wants to take x- coordinate from the set

A={0,1,2,3,5} and y- coordinate from the set B={-3,-2,-1,0,1,2,3}

(i)How many ordered pairs Neha can make from A to B?

(a)25 (b)30 (c)35 (d)40

(ii) How many ordered pairs Neha can make from B to A?

(a)25 (b)30 (c)35 (d)40

(iii) If a relation defined from A to B as R={(a,b):a<b ,a∈ A, b ∈ B}.Then how many elements are there in R

(a)6 (b)8 (c)12 (d)20

find domain and range:

how can you find the range and domain of root of

^{}(9-x^{2})?f(x)=3/(2-x^2) find the range and domain of the function

i) (-infinity,0]

ii) [0,infinity)

iii) R

iv) R - {x:g(x)=0, x belongs to R}

^{2})^{2}-16/ x+4If

y=(x+1)/(2x+1)=f(x)&x=g(y), then find.g(y)by using properties prove that

(i) a U b = a intersection b imlies a=b

(ii) for any sets a and b show that p(a intersection b) = p(a) itersection p (b)

(iii) if a,b And c be the sets such that aUb = aUc and a intersection b = a itersection c show that b = c

(iv) a intersection (aUb) = a and aU(a intersection b) = a

Shouldn't it be like , if A and B have one element in common then , n {(AxB) intersection (BXA)} also be one and if A and B have 2 elements in common then , n {(AxB) intersection (BXA)} be 2 and like wise for 3 ,4,5 ... But it's given that if A and B have 3 elements in common then , n {(AxB) intersection (BXA)}=9 How is this possible , we don't repeat same elements in the intersection of sets . Please someone explain clearly .

n(A)=p and N(B) = q.
