If the maximum depth of a lake is 1.333 thousand fee. how deep is it in 5,280 feet

the denominator polynomial has a higher degree than the numerator polynomial, so it will get large faster for large values of x. the result will tend to zero. hence the appropriate choice is

y = 0

the numerator changes sign at x=-9, but the denominator is always positive. hence the quotient will be negative for x < -9 and will be positive for x > -9. that is, the asymptote will be approached from below on the left, but from above on the right.
