It is +/- 11 you have to consider square root
5 and 10.
5 × 10 = 50
5 + 10 = 15
Domain is all real numbers
The input to an exponential function is the exponent
The base represents the multiplicative rate of change
Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t
You can see a = 8,000
As the fish population starts at 8,000
