Please help im confused best answer will get brainliest.

(40 points) i need some . an answer definition is appreciated as well.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
