As , the rate at which the exponential function decays to zero is much faster than the rate at which the two linear functions and grow; therefore

More rigorously, we can apply l'Hospital's rule twice to compute that

On the other hand, as , we have , , and , so

Therefore the only asymptote of the function is the line .
