Question

I only need the explanation of number 8. I do not know how to do it. Thanks

Step 1

As per norms, the subparts for question 8 are answered.To analyze the given relation f.

Step 2

f , being a relation from O to N is a subset of O x N (the cartesian product). As f is defined as square root, the elements -32,-8,-2 and -1/2 are n...
