Which of the following correspondences can be called a function?
(A) `f(x)=x^(3),{-1,0,1}to{-1 ,0,1,2,3}`
(B)`f(x)=+-sqrt(x),{0,1,4}to{-2,-1,0,1,2}`
(C)`f(x)=sqrt(x),{0,1,4}to{-2,-1,0,1,2}`
(D) `f(x)=-sqrt(x),{0,1,4}to{-2,-1,0,1,2}` .

Explanation

To determine which of the given correspondences can be classified as a function, we need to analyze each option based on the definition of a function. A correspondence is a function if every element in the domain is associated with exactly one element in the range.

### Step-by-Step Solution:

1. **Option (A):**
- Function: \( f(x) = x^3 \)
- Domain: \{ -1, 0, 1 \}
- Calculation:
