Anew car that sells for 18,000 depreciates 25% each year for 4 years. write an exponential function

Step-by-step explanation:

Y=ab^x

y=18,000(1-.25)^x

y=18,000(.75)^x

just plug 4 in for x

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

think about it deeply and passionately about this property

i am sorry
