I assume you want
Lim 9 sqrt(x^2-1)/(x+4)
x-> -inf
When x becomes very large and negative, the numerator approaches 9|x| (assuming you take only the positive square root) and the denominator approaches x. The fraction therefore approaches -9.
Evaluate the following limit:
lim x --> negative infinity
9 square root over x^2-1
divided by
x + 4
