Select all the correct answers.
natalie buys a new car. in the first month, the odometer on the car records 800 miles. from past experience, she expects to drive 900 miles per month.
select all the functions that can be used to find the number of miles, f(n), recorded on the odometer after n months.

Step-by-step explanation:

The total mileage by month is an arithmetic sequence with a first term of 800 and a common difference of 900. Using the general form for such a sequence, ...

  an = a1 +d(n -1)

  an = 800 +900(n -1) = 900n -100

Then, as a function of n, this can be written ...

  f(n) = 900n -100

__

When considered as a recursive relation, we find the first term is still 800:

  f(1) = 800

and that each term is 900 more than the previous one:

  f(n) = f(n-1) +900 . . . . for n ≥ 2

You have to consider that many of the various answer choices are corruptions of one or the other of these forms, so you must examine them carefully.

0.85 or 85%
