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.
The question isn't very clear to me but i'll try it out.

Answer:
Ms. Carger would have sent
emails in x minutes
Step-by-step explanation:
Firstly, Ms. Carger takes her 3 minutes to start up her computer and log-in to her email.
Therefore in x minutes, after starting up her computer and logging-in to her email, she would have x minutes minus the time used to start up her computer and log-in to her email. this implies she would have (x-3) minutes left for sending emails.
Since it takes 7 minutes to write and send each email, in (x-3) minutes she would be able to send only
emails.
Therefore equation to represent the number of emails she can send in x minutes is
emails
