PreTest Questions

Pretest

The next five questions refer to the following graph describing the profile of a surface: the y-axis represents height and the x-axis represents distance.

Graph 9: First graph of the pretest

1. How many relative maxima (locations where a point has a greater y-axis value than the points to either side) are there?
0 1 2 3 4 5 6 7

2. The absolute maximum (greatest y value) is at which point?
0 1 2 3 4 5 6 7

3. The absolute minimum (lowest y value) is at which point?
0 1 2 3 4 5 6 7

4. The Largest magnitude slope (greatest change in y for a change in x) occurs where?
Between points 1 and 2. Between points 2 and 3.
Between points 3 and 4. Between points 4 and 5.
Between points 5 and 6. Between points 6 and 7.

5. The following graph is of an object's motion. The y-axis represents the objects distance, and the x-axis represents time.
Graph 10: Second graph of the pretest
Which sentence is the best interpretation of the graph?
A: The object is moving with a constant, non-zero acceleration.
B: The object does not move.
C: The object is moving with a decreasing velocity.
D: The object is moving with a constant velocity.
E: The object is moving with a decreasing acceleration.
