Question

Use the given predicates and the math editor to write the following sentence in logical form using any appropriate quantifiers and connective. S(x) : X is a student F(x) : x is a faculty member A(x,y) : X Has asked y a question

Answer 1

we have the function f(x)

$f\left(x\right)=\left|\frac{x+1}{2}\right|$

Remember that

A function is said to be bijective or bijection, if a function satisfies both the injective (one-to-one function) and surjective function (onto function) properties

In this problem

The given function is not a one-to-one function (because for one value of the function f(x) there are two values of x)

see the graph below

therefore

The answer is

Is not a bijective function
