Answer:

The base of the exponential function is 0.90

Step-by-step explanation:

we know that

The exponential function that models this situation is equal to  

V(x)=P(1-r)^{x}  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

P=\$7,000\\r=10\%=0.10

substitute

V=7,000(1-0.10)^{x}

V=7,000(0.90)^{x}

therefore

The base of the exponential function is 0.90
