Question
**Determine the end behavior of the following function as \( x \to -\infty \):**

\[ 
r(x) = \frac{\sqrt{49x^2 - 3}}{-9x - 3} 
\]

This expression represents a rational function where the numerator contains a square root of a quadratic term, and the denominator is a linear expression. To analyze the end behavior of \( r(x) \) as \( x \) approaches negative infinity, it is important to consider the leading terms of both the numerator and the denominator.

For the numerator, \( \sqrt{49x^2 - 3} \), the dominant term as \( x \) becomes very large (in magnitude) is \( \sqrt{49x^2} = 7|x| \). Since \( x \) approaches negative infinity, this simplifies to \( 7(-x) \).

For the denominator, \(-9x - 3\), the dominant term is \(-9x\).

Thus, the function simplifies to:

\[
r(x) \approx \frac{7(-x)}{-9x} = \frac{-7x}{-9x} = \frac{7}{9}
\]

Therefore, the end behavior of the function as \( x \to -\infty \) is that \( r(x) \) approaches \(\frac{7}{9}\).
