Understanding the Parking Cost Structure

At an airport parking garage, the cost to park is $15 for the first day and $10 for each subsequent day. This means that the total parking cost, denoted as $p(n)$ , depends on the number of days, $n$ , the car is parked. In this scenario, we need to select all the functions that can be used to find the total parking cost.

Function 1: Linear Function

A linear function is a function that can be written in the form $f(x) = mx + b$ , where $m$ is the slope and $b$ is the y-intercept. In this case, the total parking cost can be represented by a linear function:

p(n) = 15 + 10(n - 1)

This function represents the total parking cost as a linear function of the number of days, $n$ . The slope of the function is $10$ , which represents the cost per day after the first day. The y-intercept is $15$ , which represents the cost for the first day.

Function 2: Quadratic Function

A quadratic function is a function that can be written in the form $f(x) = ax^2 + bx + c$ , where $a$ , $b$ , and $c$ are constants. In this case, the total parking cost can be represented by a quadratic function:

p(n) = 5n^2 - 5n + 15

This function represents the total parking cost as a quadratic function of the number of days, $n$ . The coefficient of the quadratic term is $5$ , which represents the cost per day squared. The linear term is $-5$ , which represents the cost per day. The constant term is $15$ , which represents the cost for the first day.

Function 3: Piecewise Function

A piecewise function is a function that is defined by multiple sub-functions, each of which is defined on a specific interval. In this case, the total parking cost can be represented by a piecewise function:

p(n) = \begin{cases} 15 & \text{if } n = 1 \\ 25 & \text{if } n > 1 \end{cases}

This function represents the total parking cost as a piecewise function of the number of days, $n$ . If the number of days is $1$ , the total parking cost is $15$ . If the number of days is greater than $1$ , the total parking cost is $25$ .

Function 4: Recursive Function

A recursive function is a function that is defined in terms of itself. In this case, the total parking cost can be represented by a recursive function:

p(n) = \begin{cases} 15 & \text{if } n = 1 \\ p(n - 1) + 10 & \text{if } n > 1 \end{cases}

This function represents the total parking cost as a recursive function of the number of days, $n$ . If the number of days is $1$ , the total parking cost is $15$ . If the number of days is greater than $1$ , the total parking cost is the sum of the cost for the previous day and $10$ .

Conclusion

In conclusion, the total parking cost at an airport garage can be represented by multiple functions, including linear, quadratic, piecewise, and recursive functions. Each of these functions has its own advantages and disadvantages, and the choice of function depends on the specific requirements of the problem.

Recommendations

Based on the analysis above, we recommend the following:

Use a linear function to represent the total parking cost if the number of days is small and the cost per day is constant.
Use a quadratic function to represent the total parking cost if the number of days is large and the cost per day is not constant.
Use a piecewise function to represent the total parking cost if the number of days is small and the cost per day is different for each day.
Use a recursive function to represent the total parking cost if the number of days is large and the cost per day is different for each day.

Final Answer

The final answer is:

Linear function: $p(n) = 15 + 10(n - 1)$
Quadratic function: $p(n) = 5n^2 - 5n + 15$
Piecewise function: $p(n) = \begin{cases} 15 & \text{if } n = 1 \\ 25 & \text{if } n > 1 \end{cases}$
Recursive function: $p(n) = \begin{cases} 15 & \text{if } n = 1 \\ p(n - 1) + 10 & \text{if } n > 1 \end{cases}$
