The answer is:

D - Neither A nor B

-Neither of the ordered pairs shows a straight linear line, and thus, they're not a function.

Edit 3/4/19: D is <em>not</em> the correct answer! I took the test, and it was the only question I had gotten wrong. Neither this answer or the answer above is correct.

Answer:

The correct option is 4. Neither A nor B represents a function.

Step-by-step explanation:

The given sets of ordered pairs are

A=\{(1,-5), (8,-5), (8,7), (2,9)\}

B=\{(7,-4), (7,-2), (6,-3), (-9,5)\}

A set of ordered pairs represents a function if there exist unique outputs for all inputs. It means for each values of x there exist, a unique value of y.

In set A the value of y-coordinates are -5 and 7 at x=8.

At x=8, there exist more than one value of y, so the set A is not a function.

In set B the value of y-coordinates are -4 and -2 at x=7.

At x=7, there exist more than one value of y, so the set B is not a function.

Therefore neither A nor B represents a function and option 4 is correct.

1 3/7=1.43...

so 1.38, 1.43, 1.40
the greates is .43 then .40 then .38 so the order is
