Limit X Cubed Div X
1. **State the problem:** We need to find the limit $$\lim_{x \to 0} \frac{x^3}{x}$$.
2. **Simplify the expression:** Since $x \neq 0$ in the limit process (we approach 0 but never equal to 0), we can simplify:
$$\frac{x^3}{x} = x^{3-1} = x^2$$
3. **Rewrite the limit:** Now the limit becomes:
$$\lim_{x \to 0} x^2$$
4. **Evaluate the limit:** As $x$ approaches 0, $x^2$ approaches 0 because squaring a number close to zero makes it even closer to zero.
5. **Conclusion:** Therefore,
$$\lim_{x \to 0} \frac{x^3}{x} = 0$$
This limit exists and equals 0.
6. **Graph explanation:** The function simplifies to $y = x^2$, which is a parabola opening upwards with vertex at the origin. The graph is continuous and smooth at $x=0$, confirming the limit value.
