Examine whether the function f given by `f(x)=x^2` is continuous at `x = 0`.

Explanation

To determine whether the function \( f(x) = x^2 \) is continuous at \( x = 0 \), we need to follow these steps:

### Step 1: Find the functional value at \( x = 0 \)
We start by calculating the value of the function at \( x = 0 \):
\[ f(0) = 0^2 = 0 \]
