Consider the following cost functions.
c. Interpret the values obtained in part (b).
C(x) = 500+0.02x, 0≤x≤2000, a=1000

검증된 단계별 안내
1
First, identify the cost function given: C(x) = 500 + 0.02x, where x represents the number of units produced.
Next, understand the range of x, which is 0 ≤ x ≤ 2000. This means the function is valid for production levels between 0 and 2000 units.
In part (b), you would typically be asked to evaluate the cost function at a specific value of x, which in this case is a = 1000. Substitute x = 1000 into the cost function to find C(1000).
Calculate C(1000) using the formula: C(1000) = 500 + 0.02 * 1000. This will give you the total cost when 1000 units are produced.
Interpret the result obtained from C(1000). The value represents the total cost of producing 1000 units, which includes a fixed cost of 500 and a variable cost that depends on the number of units produced.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cost Function

A cost function represents the total cost incurred by a business in producing a certain quantity of goods, denoted as C(x). In this case, C(x) = 500 + 0.02x indicates that there is a fixed cost of 500 and a variable cost of 0.02 per unit produced. Understanding this function is crucial for analyzing how costs change with production levels.

Interpretation of Values

Interpreting values from a cost function involves understanding what the numerical outputs signify in a real-world context. For instance, in part (b), if a specific value of x is substituted into C(x), the resulting cost can be analyzed to determine the financial implications of producing that quantity, including profitability and cost management.

Domain of the Function

The domain of a function specifies the set of input values for which the function is defined. In this case, the domain is 0 ≤ x ≤ 2000, meaning the cost function is only applicable for production levels between 0 and 2000 units. Recognizing the domain is essential for ensuring that any analysis or interpretation of the cost function remains relevant and valid within the specified limits.
