Prоve, оr prоvide а counterexаmple to disprove, the following stаtement: “The function f : ℝ ⟶ ℤ defined by f(x) = ⌊ 2x ⌋ is a bijection.” Use good proof technique. Remember that a bijection is both one-to-one (injective) and onto (surjective). To prove, you must demonstrate both properties are true; to disprove, you only need a counterexample that shows one of the properties is not valid. Grading rubric:1 pt. Indicate whether you will be proving or disproving the assertion. Also, if proving, state both definitions, one-to-one and onto; if disproving, state the definition you plan to disprove. 1 pt. State any givens and assumptions.1 pt. Clearly explain your reasoning.1 pt. Remember to state the final conclusion at the end of the proof. Note: To avoid the need for typing special symbols, instead of using the floor symbols in the function definition ⌊ 2x ⌋ you may use the expression ‘floor of ( 2x )’.
