25. Write the polynomial of least degree that represents the graph.

Step 1 ：The question seems to be incomplete. It mentions a graph, but no graph is provided. In order to write the polynomial of least degree that represents a graph, we would need to know the key features of the graph such as its x-intercepts, y-intercepts, turning points, and end behavior.

Step 2 ：Without this information, it's impossible to write a specific polynomial. However, I can provide a general method for writing a polynomial given these features.

Step 3 ：This function generates a polynomial of least degree given its x-intercepts. The x-intercepts are the roots of the polynomial, so each \((x - root)\) term represents a factor of the polynomial. The degree of the polynomial is the number of these factors.

Step 4 ：Without a specific graph or set of x-intercepts, we cannot provide a specific polynomial of least degree.

Step 5 ：\(\boxed{\text{Final Answer: Without a specific graph or set of x-intercepts, we cannot provide a specific polynomial of least degree.}}\)
