Question

Is
f(x)=$\frac{x}{2}$
a bijective function? Pls give a proper answer​

Answer 1

Answer:

In mathematics, a bijective function or bijection is a function f : A → B that is both an injection and a surjection. This is equivalent to the following statement: for every element b in the codomain B, there is exactly one element a in the domain A such that f(a)=b.
