The composition of a function and its inverse is
always
If the graph of an inverse passes the
you know that the inverse
is a function

The range values of an inverse are the
values of the original function.
The graph of an inverse is the reflection of the
graph of the function over the line

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
