Question

Chapter 3.3, Problem 15Q

(a)

To determine

To identify: The variables which is independent and dependent.

(a)

Expert Solution

Answer to Problem 15Q

The dependent variable is m and independent variable is r .

Explanation of Solution

Given:

The function is m=30−3r for the amount of money with r video games.

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 r video games.

The amount of money totally depends on the video games and r is free from any dependency.

Therefore, the dependent variable is m and the independent variable is r as per the definition of dependent and independent variables.

(b)

To determine

To find: The domain and the range of the function and check whether the domain is discrete or continuous.

(b)

Expert Solution

Answer to Problem 15Q

The domain of the function is 0≤x≤10 , the range of the function is 0≤y≤30 and the domain is discrete.

Explanation of Solution

Calculation:

The domain of any function are those values that is defined on the function.

In the given equation y=30−3r , the variable r represents the number of video games and the variable y represents the amount of money.

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 x=11 that is not possible.

The value of r is defined for the whole numbers until 10.

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 0≤y≤30 since the amount of money cannot be negative.

The half video game is not possible to renting that means the domain is the discrete.

Conclusion:

Thus, the domain of the function is 0≤x≤10 , the range of the function is 0≤y≤30 and the domain is discrete.
