Question

please help. Determine the growth or decay factor and the growth/decay rate in percentage form:

a)f(t)=100 x 1.06^t

b)r(t)=45.9 x 0.95^t

c)g(t)=25 x 0.8^t

Answer 1

base > 1 means growth
base < 1 means decay assuming positive exponent
base is whatever number is being raised to the t power

rate = |1-base|
percentage form means rate X100 add %

Answer 2

oops
rate = base - 1
decay will have neg rate
