1. **State the problem:** Analyze the key features of the function $$g(x) = \sqrt[3]{x - 8} + 4$$ and determine which statements A to E are true.
2. **Recall the parent function:** The parent cube root function is $$f(x) = \sqrt[3]{x}$$.
- Domain: all real numbers
- Range: all real numbers
- No absolute minimum or maximum
- Graph passes through origin (0,0)
3. **Analyze transformations:**
- Inside the cube root, $$x - 8$$ means a horizontal shift **right** by 8 units.
- The $$+4$$ outside means a vertical shift **up** by 4 units.
4. **Domain of $$g(x)$$:**
- Cube root functions are defined for all real numbers.
- Since $$x - 8$$ is inside the cube root, domain is all real numbers.
- So, domain is $$(-\infty, \infty)$$, not $$x \geq 8$$.
5. **Range of $$g(x)$$:**
- Cube root functions have range all real numbers.
- Vertical shift up by 4 does not change range.
- So, range is all real numbers.
6. **Absolute minimum:**
- Cube root functions have no absolute minimum or maximum.
- So, no absolute minimum at $$x=8$$.
7. **Behavior as $$x \to \infty$$:**
- As $$x \to \infty$$, $$x - 8 \to \infty$$, so $$\sqrt[3]{x - 8} \to \infty$$.
- Adding 4 shifts the output up but does not change the limit.
- So, $$g(x) \to \infty$$ as $$x \to \infty$$.
8. **Summary of statements:**
- A: True (range is all real numbers)
- B: False (no absolute minimum)
- C: False (domain is all real numbers)
- D: False (graph is shifted right 8 units, not left)
- E: True (as $$x \to \infty$$, $$g(x) \to \infty$$)
**Final answers:** A and E are true.
