Sketch the graph of `y = |x + 3|`and evaluate`int_-6 ^0|x+3|dx`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the Function
The function we need to sketch is \( y = |x + 3| \). The absolute value function can be rewritten based on the value of \( x \):
- When \( x + 3 \geq 0 \) (i.e., \( x \geq -3 \)), \( |x + 3| = x + 3 \).
- When \( x + 3 < 0 \) (i.e., \( x < -3 \)), \( |x + 3| = -(x + 3) = -x - 3 \).
