### Tutorial Exercise

Sketch the region bounded by the curves, and visually estimate the location of the centroid. Then find the exact coordinates of the centroid.

\[ y = 4 - x^2 \]
\[ y = 0 \]

### Step 1

Since the region is symmetric about the y-axis, we know that \( \bar{x} \) = ____.

#### Diagram Explanation:

The diagram displays a graph of the curves \( y = 4 - x^2 \) and \( y = 0 \). The shaded region represents the area bounded by these curves.

- The graph of \( y = 4 - x^2 \) is a downward-opening parabola with its vertex at the point (0, 4).
- The parabola intersects the x-axis at points \( x = -2 \) and \( x = 2 \), completing the boundary of the shaded region.
- The \( y = 0 \) curve is the x-axis, serving as the lower boundary for the shaded region between \( x = -2 \) and \( x = 2 \).

The curve forms a symmetric shape about the y-axis.
