R- {(x, y): y = 1x1,x - 1. Then the number of elements in the power set of Ris
1)32 2)16 3)8 ) 64​

Answer 1

Answer:

ANSWER

R={(0,5),(0,−5),(3,4),(−3,4),(3,−4),(−3,−4),(4,3),(−4,3),(4,−3),(−4,3),(5,0),(−5,0)}

R

−1

={(5,0),(−5,0),(4,3),(4,−3),(−4,3),(−4,−3),(3,4),(3,−4),(−3,4),(3,−4),(0,5),(0,−5)}

Therefore domain of R≡{0,3,−3,−4,4,−5,−5}= domain of R

−1
