The table below shows the estimated population of fish living in the local lake as determined by the local
environmental council every 10 years between 1960 and
1990. The equation y = 1500(0.9) describes the curve of
best fit for the fish population (). Let x represent the
number of 10-year intervals since 1960.

Using this equation, what is the approximate predicted
population of fish living in the lake in the year 2020?
