Cube Root Power 1F2F7D
1. **State the problem:** We are given the function $$y = 3 \sqrt[3]{x^5}$$ and want to understand its shape and behavior.
2. **Rewrite the function using exponent rules:** The cube root of $$x^5$$ can be written as $$x^{\frac{5}{3}}$$. So the function becomes $$y = 3x^{\frac{5}{3}}$$.
3. **Important rules:**
- The exponent $$\frac{5}{3}$$ means the fifth power of $$x$$ is taken first, then the cube root.
- Since the root is odd (cube root), the function is defined for all real $$x$$, including negative values.
4. **Analyze the function:**
- For $$x > 0$$, $$y$$ increases as $$x$$ increases because $$x^{\frac{5}{3}}$$ grows.
- For $$x < 0$$, since the cube root of a negative number is negative, $$y$$ will be negative but still defined.
- The coefficient 3 stretches the graph vertically by a factor of 3.
5. **Graph shape:**
- The graph passes through the origin (0,0).
- It is increasing for all $$x$$.
- The curve is steeper than $$y = x^{\frac{1}{3}}$$ because of the higher exponent.
**Final function:** $$y = 3x^{\frac{5}{3}}$$
