Question

The equation on the graph reads f ( x ) = 9 - x2. What is the total area of the shaded regions?

The image displays a graph of the quadratic function \( f(x) = 9 - x^2 \). This is a parabola that opens downwards. Key features of the graph include:

- **Vertex**: The peak of the parabola is at the point (0, 9) on the y-axis.
- **Axis of Symmetry**: The graph is symmetric around the y-axis, which is the line \( x = 0 \).
- **Intercepts**:
  - **Y-intercept**: The graph intercepts the y-axis at \( y = 9 \).
  - **X-intercepts**: The parabola crosses the x-axis at \( x = -3 \) and \( x = 3 \).

The shaded area represents the region under the curve and above the x-axis. This area is symmetric with respect to the y-axis, reflecting the parabola's symmetrical properties. The grid lines are spaced at intervals of 1 on both the x and y axes, providing a reference for measurement and symmetry.
