Q)

Let R denotes the set of all real numbers and R+ denote the set of all positive real numbers. For the subsets A and B of R define f:AB by f(x)=x2 for xA. Observe the two lists given below:

List I List II

(i) f is one-one and onto if

(ii) f is one-one but not onto if 

(iii) f is onto but not one-one if

(iv) f is neither one-one nor onto if 

(a) A=R+,B=R

(b) A=B=R

(c) A=R,B=R+

(d) A=B=R=

The correct matching of list I to List II is

      (i)    (ii)    (iii)   (iv)

(1)  (a)  (b)   (c)    (d)

(2)  (d)  (b)   (a)    (c)

(3)  (d)  (a)   (c)    (b)

(4)   (d) (b)   (c)    (a)
