The function #c=45n+5# can be used to determine the cost, c, for a person to purchase n tickets to a concert. Each person can purchase at most 6 tickets. What is an appropriate domain for the function?
Basically the 'domain' is the set of input values. In other wards it is all the permitted independent variable values.
Suppose you had the equation:
Then for this equation the domain is all the values that may be assigned to the independent variable
Domain: The values you may chose to assign.
Range: The related answers.
For the given equation:
We are told that no more than 6 tickets may be purchased by any one person. So
So the domain is written as:
~~~~~~~~~~~~~~~ Memory aid ~~~~~~~~~~~~~~~~~~~~~~~~~~~
In the alphabet d for domain comes before r for range
You have to 'plug' in a value before you get your answer
So d first
and r next
