The number of a particular fish in thousands x years after 1974 can be modeled by f(x)=233(0.885)^x. estimate the year when the number of these fish reached 90 thousand.

Where is the diagram?

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.
