6,4 and or 8,7 should be the answer
Answer: (a) Yes. The table is a function.
<u>Step-by-step explanation:</u>
In order to be a function, there cannot be any duplicate x-values.
In the given table, each x-value is different so this IS a function.
Let's calculate Charlie swimming distance. Assume Charlie swimming distance is D.
D^2 = 400^2 + 100^2 => D = 412 meters
Assume d is Carter's distance.
d^2 = 400^2 + 150^2 => d = 427 meters
Carter swims more than Charlie by:
d - D = 427 - 412 = 15 meters
