Let `f: RvecRa n dg: CvecC` be two functions defined as `f(x)=x^2a n dg(x)=x^2` . Are they equal functions?

Explanation

To determine whether the functions \( f(x) = x^2 \) and \( g(x) = x^2 \) are equal, we need to analyze their definitions and domains.

### Step-by-step Solution:

1. **Identify the Functions**:
- The first function is defined as \( f: \mathbb{R} \to \mathbb{R} \) where \( f(x) = x^2 \).
- The second function is defined as \( g: \mathbb{C} \to \mathbb{C} \) where \( g(x) = x^2 \).
