Question

The function f(x)=x+1 from the set of integers to itself is onto. Is it True of False?​

Answer 1

Answer: True

Step-by-step explanation: let us consider, f(x)= y,

now, y= x+1 ⇒x=y-1 ∈ set of an integers , since x∈ set of integers

therefore, the inverse of the function belongs to on the set of integers .

so,the function f(x) from the set of integers to itself is onto.
