Which of the following function f: Z X Z → Z is not onto?a.f(a, B) = a – bb.f(a, B) = |b|c.f(a, B) = a + bd.f(a, B) = a
Question
Solution 1
The function that is not onto is b.f(a, B) = |b|.
An onto function (or surjective function) is a function where every element in the codomain is the image of at least one element from the domain. In other words, every element in the set that the function maps to (Z in this case) must be associated Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
