a glass of ice tea cost two dollars. Refills cost 25 cents each. write the rule in function notation.
is it F(x)=2+.25x?
If it is wrong can you help
correct, but that is a lot for iced tea. Here in Texas, a price like that could start a Range War, assuming it was sweetened tea, and it was summer.
lol that was funny
You're on the right track, but the function notation F(x) refers to the total cost of the ice tea, not just the cost of refills. Since the initial glass of ice tea costs $2 and each refill costs $0.25, you can write the rule in function notation as follows:
F(x) = 2 + 0.25x
In this notation, x represents the number of refills, and 0.25x represents the cost of those refills. The constant term, 2, represents the initial cost of the glass of ice tea. Adding the two together gives you the total cost, which is represented by F(x).
