Show that the given map is surjective. Please give a detailed, thorough formal explanation/proof. It's somewhat obvious it is surjective, but I don't know how to start the proof. We are supposed to take y element of codomain and show that there exists f(x) = y but where is the codomain and where is the domain? Somewhat confused since we have two binary structures. Thanks!
Homework Answers
For proving any function to be onto ,we take an arbitrary point
from codomain and we will show that there exists at least one point
in domain which corresponds that point.The whole process is given
below ?
