Step 1.2.1

Factor $x$ out of $x^{4}$ .

$lim_{x \to 0^{-}} \frac{x \cdot 6}{x \cdot x^{3}}$

Step 1.2.2

Cancel the common factor.

$lim_{x \to 0^{-}} \frac{x \cdot 6}{x \cdot x^{3}}$

Step 1.2.3

Rewrite the expression.

$lim_{x \to 0^{-}} \frac{6}{x^{3}}$

Step 2

Since the numerator is a constant and the denominator approaches $0$ when $x$ approaches $0$ from the left, the fraction $\frac{6}{x^{3}}$ approaches negative infinity.

$- \infty$
