The given text contains several questions labeled (D), (c), and (d). According to the guidelines, we will only answer the first three questions. The first three questions are:
- At which \( x \)-values does the function have local maxima?
- What is the sign of the function's leading coefficient?
- Which of the following is a possibility for the degree of the function? Choose all that apply.
The first question asks for the \( x \)-values where the function has local maxima. However, the text does not provide any specific function or additional information to determine these values. Therefore, we cannot answer this question without further details.
The second question asks about the sign of the function's leading coefficient. The text provides the answer as "Positive." Therefore, the leading coefficient of the function is positive.
The third question asks which of the following numbers could be the degree of the function: 4, 5, 6, 7, 8, 9. Without additional information about the function, we cannot determine the exact degree. However, since the leading coefficient is positive, any of these degrees could be possible.
- At which \( x \)-values does the function have local maxima?
- Not enough information provided.
- What is the sign of the function's leading coefficient?
- \(\boxed{\text{Positive}}\)
- Which of the following is a possibility for the degree of the function? Choose all that apply.
- \(\boxed{4, 5, 6, 7, 8, 9}\)
