Question 1157919
<br>
Factor the denominator to show the function as<br>
{{{7/((x+6)(x-6))}}}<br>
The graph will have vertical asymptotes at x=-6 and x=6; so the window must include both of those x values.  That eliminates answer choice C.<br>
The factors of (x+6) and (x-6) each occur only once.  That means that from one side to the other of x=-6, and from one side to the other of x=6, the sign of the function will change; so the window must display both positive and negative function values.  That eliminates answer choices A and D.<br>
The only choice left is B.<br>
Here is a graph using that window:<br>
{{{graph(400,400,-12,12,-4,4,7/(x^2-36))}}}<br>
