Question

If R ={(a,1),(b,2)} then which one is the inverse of the relation R?​

Answer 1

R’ = {(1,a) , (2,b)}

Explanation:

For us to get the inverse, we switch the places of the x and y variables

The x variable goes to the place of the y variable and the y variable goes to the place of the x variable

we have this as;

R’ = {(1,a) , (2,b)}
