`lim_(x->3)x+3`

Explanation

To solve the limit \( \lim_{x \to 3} (x + 3) \), we can follow these steps:

### Step 1: Identify the function
The function we are dealing with is \( f(x) = x + 3 \).

### Step 2: Direct substitution
Since \( f(x) \) is a polynomial function, we can directly substitute the value of \( x \) as it approaches 3.
