Answer:
exponential decay: A=(0.97)^t, y=3.7(0.2)^t,
exponential growth: y=(9/11)(4)^t, P=(7/9)(5/4)^t, V=0.8(9)^t, P=0.9(8.3)^t
neither: g(x)=2.1(x)
Step-by-step explanation:
exponential decay happens when the ratio (the value inside the parenthesis) is less than 1. exponential growth happens when the ratio is greater than 1.
