**Problem Statement:**

A golf ball is hit from the top of a cliff and lands on the green located at the bottom of the valley. The path of the golf ball can be modeled by the relation \( h(t) = -2(t - 5)^2 + 60 \) where \( h(t) \) is the height in meters above the valley and \( t \) is the time after the ball was hit, in seconds.

**Instruction:**

Sketch a graph of the situation.

**Graph Explanation:**

The provided grid should be used to sketch the graph of the function \( h(t) = -2(t - 5)^2 + 60 \). This is a quadratic function in vertex form, indicating the path of the golf ball.

Key points for sketching the graph:
1. **Vertex**: The vertex of the parabola is at \( (t, h(t)) = (5, 60) \). This represents the highest point the ball reaches.
2. **Shape**: The parabola opens downward (as indicated by the negative coefficient of the squared term).
3. **Intercepts**: The points where the parabola intersects the t-axis (i.e., \( h(t) = 0 \)) indicate the moments when the ball hits the ground.

To plot the sketch:
- Start at the vertex (5, 60).
- For corresponding \( t \) values on both sides of 5, calculate \( h(t) \) and plot these points.
- Continue plotting points until \( h(t) = 0 \) is reached both on the left and right sides of the vertex.

The final sketch should depict the trajectory of the golf ball from the moment it is hit until it lands back on the ground. The graph's x-axis represents time (in seconds), and the y-axis represents height above the valley (in meters).
