The equation, p 5000(2) represents the
population of an invasive fish species in a
large lake, t years since 2005, when the fish
population in the lake was first surveyed.
Use the graphing calculator to enter the above equation
with the value of t being replaced with -2, select the gear
icon, then the table to determine your response
For t = -2, is the fish population more or less
than 1000?
