3. write the letter of the situation next to the graph that best represents it. situation a. the height of a…

Brief Explanations:

1. For situation A, a model - rocket launched straight up first goes up (height increases) and then comes down (height decreases), which is represented by a parabolic - like curve opening downwards. The third graph shows a quantity that first increases and then decreases, so it matches situation A.
2. For situation B, a person sitting in the top row of the bleachers has a constant height above the ground. The first graph shows a horizontal line, indicating a constant value, so it matches situation B.
3. For situation C, a ball dropped from the top of a building has its height above the ground decrease over time. The second graph shows a decreasing curve, so it matches situation C.

Answer:

First graph: B. The height above the ground of a person sitting in the top row of the bleachers at a football game Second graph: C. The height of a ball above the ground after it is dropped from the top of a building Third graph: A. The height of a model rocket after it is launched straight up into the air
