* = Multiply (x)
A = y-poitent of 0
B = Multiplyer
^x = Time
y = y-poitent * multiplyer^x
1. A negative exponents suggest a time BEFORE the start of the situation.
Ex: y = 400 -(1/3)^x represents the declining bird population starting in 2015
2. t = -2 represents the bird population in 2013
Negative Exponent Rule
X^-n = 1/x | 3^-2 1/3^3 = 1/9
Power rule
(4^2)^3 = 4^6
4^2 4^2 4^2
4*4 4*4 4*4
400(1/3)^-3
400 / (1/3)^2 = 400 / 1/9
