Final answer:

The vertical asymptote of the function f(x) = -x² - 2x - 2/x - 2 is at x = 2. However, due to a potential formatting error, we cannot definitively determine the oblique asymptote without the correctly written function. To find the oblique asymptote, polynomial long division should be performed.

Step-by-step explanation:

The graph of the function f(x) = -x² - 2x - 2/x - 2 can be analyzed to determine its asymptotes. First, the vertical asymptote occurs when the denominator equals zero, which happens at x = 2. Thus, the function cannot be defined at x = 2, indicating a vertical asymptote at x = 2.

Next, to find the oblique asymptote, we would usually perform polynomial long division if the degree of the numerator is higher than the denominator. However, given that the function is written with a subtraction right before the term with the denominator, this seems to be a formatting error. Assuming the function should have the denominator as part of the polynomial, the correct interpretation would likely be f(x) = (-x² - 2x - 2)/(x - 2). If we then perform long division or synthetic division, we would get a linear term that would represent the oblique asymptote.

Unfortunately, without the correct expression, we cannot definitively find the oblique asymptote. However, given the context that we want to find a positive value with a positive slope at x = 3 and knowing typical characteristics of a quadratic function, we can infer that the slope is decreasing as x increases. Neither of the linear options provided, y = 13x or y = x², entirely fits the description of this behavior as y = 13x implies a constant slope (straight line), and y = x² implies a slope that increases with x, not decreases. Therefore, with the provided information, we cannot accurately choose an option shown in the student's provided choices for the oblique asymptote.
