Prоve, оr prоvide а counterexаmple to disprove, the following stаtement: “The function f : ℤ ⟶ ℕ defined by f(n) = n2 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 superscript exponents, you may use the expression ‘n^2’ or ‘n-squared’ to represent n2.

Although she does not drive anymore, there is a small store in her building and a bus that takes residents to a grocery store once a week. She has a son who is 50-years-old. Because she is somewhat forgetful, her son helps her with some financial matters. Two weeks ago Mrs. Brown saw her physician for her annual physical exam. She weighed 170 pounds and is 5’4” tall. Her blood pressure was 140/90 mm Hg. Results of her lab test showed normal values except for glucose at 150 mg/dl. Her physician referred her to the clinic dietitian to assess and diagnose her nutrition-related problems and plan an intervention.
