Answer:
This means that the domain of this situation is [tex]m \in [0,200][/tex], that is, you can talk between 0 and 200 minutes in the month.
Step-by-step explanation:
Ace Telecommunications charges $0.12 per minute of phone use plus a monthly service fee of $8.00 for the phone service.
This means that the cost of speaking for m minutes is given by:
[tex]C(m) = 8 + 0.12m[/tex]
You can talk for no more than 200 minutes in a month.
This means that:
[tex]m \leq 200[/tex]
What is the domain of this situation?
The domain of a function is the input variable.
In function C(m), m is the input variable, and since you can talk for no more than 200 minutes in a month, the restriction for the input is [tex]m \leq 200[/tex].
This means that the domain of this situation is [tex]m \in [0,200][/tex], that is, you can talk between 0 and 200 minutes in the month.
