The process by which we determine limits of rational functions applies equally well to ratios containing noninteger or negative powers of x: Divide numerator and denominator by the highest power of x in the denominator and proceed from there. Find the limits. $lim_{x \to \infty} \frac{x - 3}{\sqrt{4 x^{2} + 25}}$
