Step-by-step explanation:
Think that,
y=1-x
in the equation from relation R is,
y=1-x
Find the value of y for different values of x
x=-2,-1,0,1,2
y=-3,2,1,0,-1
But,-3 is not belongs to A
so,(-3,-2) is not belongs to R
then,R={(-1,2),(0,1),(1,0),(2,-1)
The range of R={2,1,0,-1}
Hope that it will help you
