Answer 1

Answer:

Domain of R-¹ is {4, 3, 2, 1} = Range of R

Step-by-step explanation:

y= 10-x/2

where both x and y are natural numbers between 1 and 10.

Clearly for x= 2, 4, 6, 8 we get values of xy as 4,

3, 2, 1.

∴ R = ( 2, 4), (4, 3), (6, 2) (8, 1)}

∴R-¹ = {(4, 2) , (3, 4),(2, 6), (1, 8)}

Domain of R is {2, 4, 6, 8}= Range of R¹

Domain of R-¹ is { 4, 3, 2, 1} = Range of R
