and why it is invertible.)
(b) What is N 17 Explain in words what does, and state the domain and range of N- Give an example

Expert Solution
Step 1
Given that N(v) denotes the number of a video in a list.
That is, for example N (Sorry) =14,
That is if we insert a video name in the Function, it will provide its number in the list. Thus we get that each element has its image in the list. Thus, N(v) is a function.
