3.A car has 86,391 miles on its odometer and accumulates an average of 260 more each week. What is the function rule that represents the total number of M miles the car will have on the odometer after w weeks? (1 point)
Responses

M(w)=86,391+260w
cap m times w is equal to 86 comma 391 plus 260 w

M(w)=86,391w+260w
cap m times w is equal to 86 comma 391 w plus 260 w

M(w)=86,391w+260
cap m times w is equal to 86 comma 391 w plus 260

M(w)=86,391+260
cap m times w is equal to 86 comma 391 plus 260

Answer 1

I can only answer the items that don’t require the missing images. For the rest I need you to upload or describe the graphs/functions.

3) Odometer problem
- Correct rule: M(w) = 86,391 + 260w
(starting miles plus 260 miles per week)

2) Ice-cream shop (description of the correct graph)
- Cost C(t) = 4 + 1·t for t = number of toppings, with 0 ≤ t ≤ 10.
- The correct graph is an increasing line with slope 1 starting at (0, 4) and ending at (10, 14). If the plot shows only integer topping counts, it will be the discrete points (0,4), (1,5), …, (10,14) (closed dots).

For questions 1, 4, and 5 I’m missing the graphs/functions. Please upload the images or paste the function equations and I’ll pick the domain/range and the profit value.
