Answer explanation
Choice A is correct. In each choice, the values of are , , and . Substituting the first value of , , for in the given inequality yields , or . Therefore, when , the corresponding value of must be greater than . Of the given choices, only choice A is a table where the value of corresponding to is greater than . To confirm that the other values of in this table and their corresponding values of are also solutions to the given inequality, the values of and in the table can be substituted for and in the given inequality. Substituting for and for in the given inequality yields , or , which is true. Substituting for and for in the given inequality yields , or , which is true. It follows that for choice A, all the values of and their corresponding values of are solutions to the given inequality.
Choice B is incorrect. Substituting for and for in the given inequality yields , or , which is false.
Choice C is incorrect. Substituting for and for in the given inequality yields , or , which is false.
Choice D is incorrect. Substituting for and for in the given inequality yields , or , which is false.
