Given the function pairs (1,5),(2,6),(4,8),(5,10), we are tasked with finding an additional ordered pair that could complete the function. The function requires that each input x corresponds to exactly one output y.

Let's evaluate each option:

A, (−1,2): This pair introduces x=−1 with y=2. Since x=−1 does not exist in the current pairs (1,5),(2,6),(4,8),(5,10), adding (−1,2) does not violate the rule of each x having a unique y.

B.(1,4): This pair suggests y=4 for x=1. However, (1,5) already exists, so addin...
