Answer:
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential decay function is equal to
[tex]y=a(1-r)^x[/tex]
where
y is the number of active members
x is the number of months
a is the initial value (y-intercept)
r is the rate of change
we have
[tex]a=7,000\\r=5\%=5/100=0.05[/tex]
substitute
[tex]y=7,000(1-0.05)^x[/tex]
[tex]y=7,000(0.95)^x[/tex]
The domain of the function is the interval [0,∞)
[tex]x\geq 0[/tex]
Remember that the number of months cannot be a negative number
Te range of the function is the interval (0,7,000]
[tex]0 < y \leq 7,000[/tex]
