Will give brainliest if correct. when graphing the function f(x) = x^2 -81 / x^2 - 11x + 18 on your graphing calculator. what is the most appropriate viewing window for determining the domain and range of the function.

Since

The only vertical asymptote is x=2. So, if you center the viewport around x=2, y=0 you can see that the function is not defined at x=2, and that the limits are negative/positive infinity as x approaches 2 from left/right.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
