Mark the correct A. onto but not one-one
B. one-one but not onto
C. one-one and onto
D. neither one-one nor onto
Answer :
Given function f: Z → Z defined as
For x = 3, f(x) = 0
For x = 5, f(x) = 0
But 3 ≠ 5
So, f is not one-one.
Y=f(x)
∵ x ϵ R ⇒ y ϵ R
∴ Domain = Range
Hence, f is not one-one but onto.
