Answer to Question #253333 in Calculus for Kenneth Pondang

Question

State the domain and range of the relations described.

y = x-1, x ≠ 2

= 1 , x = 2

Answer 1

Domain is the set of all possible inputs. In our case input is x. x can be (R\{2})∪{2} = R

Range is the set of all possible outputs. In our case output is y. y can be R\{1} for all x except of {2} and 1 for x = 2. The range of y is (R\{1})∪{1} = R
