1. The problem statement, all variables and given/known data A new car that costs $30,000 has a book value of $18,000 after 2 years. a) Find a linear model that represents the value 'V' of the care after 'x' years b) Find an exponential model of V= ab^(x) that represents the value 'V' of the car after 'x' years. 2. Relevant equations -None- 3. The attempt at a solution I found the linear model just by basic graphing knowledge and using slope formula. Linear Model: V= -6,000x + 30,000 I don't know how to find the exponential function, I know its a decay so it has to be a fraction, but how do I start it, and what is it supposed to be?
