If `f(x)={(sin3x)/x ,\ \ \ w h e n\ x!=0 1,\ \ \ w h e n\ x=0` . Find whether `f(x)` is continuous at `x=0` .

Explanation

To determine whether the function \( f(x) \) is continuous at \( x = 0 \), we need to check if the following condition holds:

\[ \lim_{x \to 0} f(x) = f(0) \]

### Step 1: Identify the function
The function is defined as follows:
