Peters of covergue does the
heby monitor provide?

Can someone check if i did this correct. it’s number 4 if you’re wondering.

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

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x
