Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is given by

where
y is the value of the home
x is the number of years
a is the initial value
r is the rate of change
we have

substitute


 
        
             
        
        
        
Only 4 because result is (x-4)(x-4) that means (x-4)^2=0 
So
X-4=0
X=4
