Answer:
It's the first option.
Step-by-step explanation:
(x^2 - 81) / (x^2 - 11x + 18)
= (x - 9)(x + 9) / (x - 9) (x + 2)
= (x + 9) / (x + 2).
So there is a vertical asymptote x = 2 and an x intercept at (0, -9). Also there is a y-intercept at -81/18 = -4.5.
So the most appropriate window is x min -10, x max 10 , y min -10, y max 10.
