Homework Statement
Find the composites for the relations defined.
R1={(x,y) member of real numbers x real numbers: y=x}
R2={(x,y) member of real numbers x real numbers: y=-5x+2}
a) R1compositeR1
b)R2compositeR2
2. The attempt at a solution
a) I was thinking that R1compositeR1={(x,y) member of real numbers x real numbers: x=y}=R1
b) I'm not to sure how to do and that's the one I need help on.
Can you please help me?
Thank you!
