function from A to A ?

Answer 1

QUESTION:
A = { –2, –1, 1, 2 } and f = {(x, 1/x ) :
x∈A}
Write down the range of f . Is a function f from A to A ?

Function :
Let A and B be any two non empty sets. A function f from A to B is a rule of correspondence that assigns each element x∈A to a unique element y∈B.
We denote y = f(x) to mean y is a function of x.

•Range : The set of all the second elements of the ordered pairs of a relation is called the range of the relation.
