Question

Range of f (x) is equal to x

Answer 1

Let R be a relation defined by f(x) = x². where x values (1,2,3).

When x = 1, then f(x) = 1
When x = 2, then f(x) = 4
Where x = 3, then f (x) = 9

Here, set {1,2,3} is domain.
Set {1,2,3,4,5,6,7,8,9} is Codomain.

Set {1,4,9} is Range of f (x) here.
