Final answer:
The profit function of a company selling cell phones for $206 each would require knowledge of the costs associated with producing the phones. Since this information is not provided, none of the multiple-choice options can be confirmed as correct without further context.
Step-by-step explanation:
The student is asking for the profit function of a cell phone manufacturer that sells phones for $206 each. The profit function is not explicitly provided in the context of the question, but the student is presented with multiple choice options. To determine the profit function, one would usually subtract the total cost from the total revenue. If x represents the number of phones sold, the total revenue would be $206x. However, without knowing the expenses associated with each phone sold or the fixed costs, it's impossible to provide an accurate profit function. Typically the profit function is in the form of P(x) = Revenue(x) - Cost(x), but for this question, such detailed information is not provided.
