Answer:
<h2> 2.32dollar/mile</h2>
Step-by-step explanation:
step one:
Given the function
y = 14 +2.31x + 4.50
we can solve for the rate of change by applying differentiation.
step two:
differentiating y which is cost with respect to x which is the miles
dy/dx= 0+2.32+0
dy/dx=2.32
Hence the rate of change of cost in the dollar to a mile is
2.32dollar/mile
Answer:
Decay function, 70% per year.
Step-by-step explanation:
A general exponential function is defined as
...(1)
where, a is initial value, |r| is rate of change and x is time in years.
If r>0, then it is a growth function and if r<0, then it is a decay function.
The given function is

It can be rewritten as

...(2)
On comparing (1) and (2), we get

Since r<0, therefore the given function is a decay function.

Therefore, the given function decreasing by 70% per year.
