Question

if A ={x:x € W, x<2}​

Answer 1

We have 3

2

+4

=25 or, 4

2

+3

2

=25 and 0

2

+(5)

2

=25 or, 5

2

+0

2

=25.

So the domain of R is {0,3,4,5}. [ Values corresponding to x for x being whole number]

And the range is {0,3,4,5}. [ Values corresponding to y for y being whole number]

Answer 2

Answer:

We have, P={x: x<3,x ∈ N} = {1,2}

And Q = {x :x≤ 2,x∈ W] = {0,1,2}

P∪Q= {0, 1,2} and P ∩ Q= {1,2}

(P ∪ Q) x (P ∩ Q) = {0,1, 2} x {1,2}

= {(0,1), (0, 2), (1,1), (1,2), (2,1), (2, 2)}
