(a)
Answer to Problem 15Q
The dependent variable is
Explanation of Solution
Given:
The function is
The dependent variables are those variables that depends on another variable and changes accordingly. It provides output values for the function.
On the other hand, the independent variable is free from the dependency on the another variable and it is the input variable of the function.
In the given problem it can be observed that the amount of money increases and decreases with
The amount of money totally depends on the video games and
Therefore, the dependent variable is
(b)
To find: The domain and the range of the function and check whether the domain is discrete or continuous.
(b)
Answer to Problem 15Q
The domain of the function is
Explanation of Solution
Calculation:
The domain of any function are those values that is defined on the function.
In the given equation
The person can rent no video game, one video game or more than one that means the number of movie tickets is the positive numbers and 0.
The amount of money is negative if the value of
The value of
Therefore, the domain of the function is the set of whole numbers until 10 as per the definition of domain.
The range of any function is the set of output values of the function.
According to the domain, the range is
The half video game is not possible to renting that means the domain is the discrete.
Conclusion:
Thus, the domain of the function is
