Answer:

This function only has a horizontal asymptote #y=0#

Explanation:

Given:

#g(t) = (t-6)/(t^2+36)#

Note that the denominator is positive for any real value of #t#.

Hence this rational function has no vertical asymptotes and no holes.

The degree of the denominator is also greater than the numerator. So it has no blique asymptotes - only the horizontal asymptote #y=0#.

#lim_(t->+-oo) (t-6)/(t^2+36) = lim_(t->+-oo) (1/t-6/t^2)/(1+36/t^2) = (0-0)/(1+0) = 0#

graph{(x-6)/(x^2+36) [-20, 30, -0.3, 0.3]}
