Algebra-1

To determine if the given set of ordered pairs represents a function, we need to check if each input x corresponds to exactly one output y.

The ordered pairs given are:

(−17, 1.05),(−54, 3.76),(−21, 5.89),(−66, 9.14),(−21, 0.70)

Let's identify the unique x-values:

x=−17 appears in the pair (−17,1.05)

x=−54 appears in the pair (−54,3.76) ...
