__ 1. Which of the ordered pairs does not represent a function. A (-7,-8)(-2,-4)(-7,-3)(-9,-7) B (7,-6)(6,-5)(-9,-9)(2,-5) c (-4,9)(-2,-8)(7,0)(4,8) D (0,-1)(-9,-5)(9,-5)(3,-8) E. None of the above

To determine which ordered pairs do not represent a function, we need to check if each input (x-value) has only one output (y-value).<br /><br />Let's analyze each option:<br /><br />A. $(-7,-8)(-2,-4)(-7,-3)(-9,-7)$<br />In this case, the input -7 has two different outputs (-8 and -3). Therefore, option A does not represent a function.<br /><br />B. $(7,-6)(6,-5)(-9,-9)(2,-5)$<br />In this case, each input has only one output. Therefore, option B represents a function.<br /><br />C. $(-4,9)(-2,-8)(7,0)(4,8)$<br />In this case, each input has only one output. Therefore, option C represents a function.<br /><br />D. $(0,-1)(-9,-5)(9,-5)(3,-8)$<br />In this case, each input has only one output. Therefore, option D represents a function.<br /><br />E. None of the above<br />Since option A does not represent a function, option E is incorrect.<br /><br />Therefore, the correct answer is A.
