Complete Question
When the Olympic Games were held outside Mexico City in 1968, there was much discussion about the effect the high altitude (7340 feet) would have on the athletes. Assuming air pressure decays exponentially by 0.5% every 100 feet, by what percentage is air pressure reduced by moving from sea level to Mexico City?
Round your answer to one decimal place.
....... %
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The height of Mexico city is h = 7340 feet
The rate at which air pressure decays is 0.5% per 100 feet
From the data given

ANSWER
First choice
EXPLANATION
The graph of f(x) and

are symmetric about the line y=x.
This means that the graph of

is the reflection of f(x) in the line y=x.
This explains why the composition of a function and its inverse yields x, as the result.
The first choice is correct.
