The population of cats that are rescued every year is currently 50,000 and declines at a rate of 1.2% every year. this modelsa) exponential growth.
b. exponential decay.

The correct answer is:  [B]:  "exponential decay" .

    Note that "decline" would suggest "decay";  whereas "increase" would suggest "growth".

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

It says in the questions that it is 6.5?
