Check whether the function has (have) y-symmetry or origin symmetry: ` f(x) = x^(2) sin x`.

Explanation

To determine whether the function \( f(x) = x^2 \sin x \) has y-axis symmetry or origin symmetry, we will follow these steps:

### Step 1: Check for y-axis symmetry
A function has y-axis symmetry if \( f(-x) = f(x) \).

1. **Calculate \( f(-x) \)**:
\[
f(-x) = (-x)^2 \sin(-x)
