Prоve, оr prоvide а counterexаmple to disprove, the following stаtement: “The function f : ℝ ⟶ ℤ, defined by f(x) = ⌊ x + 2 ⌋ is onto.” Notice the use of the floor function in the definition of function f. Use good proof technique. Grading rubric:1 pt. State the definition of onto at the beginning, then prove or 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.
