All right, so we have our question going to write as chapter 4, section 6, number 60a.
00:25
Now, if it depreciates by 66 -750, that's going to be a negative, times t plus the initial starting point, which is 54 ,000.
00:39
So we have a linear model.
00:42
We now have b.
00:46
We're going to write an exponential function, so that's going to be y equals our initial value, 54 ,000, b and t.
00:56
So b is going to be a rate of depreciation, which is 70 % 0 .7 of t to the power of t.

So now we have that model, and we can look at c to the nearest dollar, determine the value of the vehicle after four years and eight years, using the linear model.

F of 4 to determine f of 8...
