Math Problem Statement
What is the range of the function y = ³√(x) + 8?
Solution
Let's analyze the function given in the problem:
Step 1: Understanding the Cube Root Function
The cube root function, , has a domain and range of all real numbers:
Since cube roots are defined for all real values of , adding 8 simply shifts the function vertically by 8 units. This does not affect the range—it remains all real numbers.
Step 2: Identifying the Correct Answer
From the multiple-choice options:
- ✅ (Correct)
- ❌ (Incorrect, since can take any negative value)
- **( 0 \leq y <
