Triangle abc has coordinates a(1,-1), b(0,2) and c(2,1) and it is reflecting over the line y = -x to form triangle a’b’c’ that are the coordinates of triangle a’b’c’

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
