Let's break down the contents of the image you've uploaded. I can assist you in understanding the questions and solving them based on the graph provided.

1. The degree of the polynomial function (Q2):

• The graph provided is of a polynomial function, and the degree can be determined by analyzing the number of turning points or the general shape of the curve.
• Since the graph shows 4 turning points, this suggests that the degree of the polynomial is one more than the number of turning points, i.e., the degree is 5.

2. The end behavior of the function (Q3 and Q4):

• To describe the end behavior of a polynomial function, observe how the graph behaves as $x \to \infty$ (positive infinity) and $x \to -\infty$ (negative infinity).
• For a polynomial of degree 5 with a negative leading coefficient (based on the fact that the graph falls as $x \to \infty$), the end behavior can be described as:
  • As $x \to -\infty$, $f(x) \to +\infty$.
  • As $x \to +\infty$, $f(x) \to -\infty$.

3. The x-intercepts of the function (Q5):

• The x-intercepts (or roots) of the function are the points where the graph crosses the x-axis. Based on the graph, it seems to cross the x-axis at several points. You will need to estimate these values based on the graph.

4. Vertical asymptote and rational function (Q6-Q9):

• Since the graph is that of a polynomial, it typically does not have vertical asymptotes. Rational functions, which involve divisions, are the ones that exhibit vertical asymptotes, not polynomials.

5. Domain and range of the polynomial function (Q10):

• The domain of any polynomial function is all real numbers, i.e., $(-\infty, +\infty)$.
• The range of the function can be determined by the graph's minimum and maximum values. However, without more details from the graph, we can only approximate based on its general behavior.

Do you want more details on specific questions or explanations on polynomial properties?

Here are 5 additional questions related to this topic:

1. How do you calculate the degree of a polynomial from its equation?
2. What are the key differences between polynomial and rational functions?
3. How can we determine the turning points of a polynomial function algebraically?
4. What role does the leading coefficient play in determining end behavior?
5. How does factoring help in finding the roots of a polynomial function?

Tip: When analyzing a graph, always check how the graph behaves at extreme values of $x$ (end behavior) to help determine the degree and leading coefficient of the function.
