If t: (x, y) → (x - 7, y + 2), then t -1: (x, y) → a.( -x/7 , y/2) , 2y) c.(x - 7, y - 2) d.(x + 7, y - 2)

How do i do this activity, is appreciated

Which inequality has a dashed boundary line when graphed ?

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.
