Prove, or provide a counterexample to disprove, the following statement: “The function f : ℝ ⟶ ℤ, defined by f(x) = ⌊ x + 2 ⌋ is one-to-one.” 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 one-to-one 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. Note: To avoid the need for typing special symbols, instead of using the floor symbols in the function definition ⌊ x + 2 ⌋ you may use the expression ‘floor of ( x + 2 )’.
