Hi,

I hope someone can help me figure out why the range for this word problem:

Note: knowing example 3 isn't necessary.

I have already developed the right equation for this word problem, which is f(x) = 5000 - 25t - 1000cos((pi/6)t). I now just need to determine what the range is. Apparently the range is from 0 to 3850. I personally do not see where the number came from. Can someone please help me?

Sincerely,

Olivia
