Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:
In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:
Hence, the answer is:
f(x) = 4cos(8/3 x) - 3

- The speed of Mei is 6 pages per day.
- The total time is 30 days.
- The number of pages written in 30 days by Mei is 30*6.
- Mei's number of pages written in 30 days is 180.
- Mei's total number of pages that she will have written at the end of 30 days is 250 + 180.
- The total number of pages that Mei will have written at the end of 30 days is 430.
