Question

f(A)=|A|. where A is a matrix then it is one-one function or not?​

Answer 1

Step-by-step explanation:

Consider the function x → f(x) = y with the domain A and co-domain B. If for each x ε A there exist only one image y ε B and each y ε B has a unique pre-image x ε A (i.e. no two elements of A have the same image in B), then f is said to be one-one function. Otherwise f is many-to-one function.
