Question

A graph shows time (seconds) labeled 2 to 4 on the horizontal axis and height (meters) on the vertical axis. A line of orange dots increases from 0 to 3 seconds and decreases from 3 to 7 seconds.
Which statements are true regarding the data represented by the scatterplot of projectile motion? Check all that apply.

The data shows an exponential relationship.
The data shows a quadratic relationship.
The data shows a linear relationship.
The height will increase over time at a constant rate of change.
The change in height compared to the change in time is not constant.

Answer 1

Correct choices:
- The data shows a quadratic relationship. (True: projectile height vs time is a parabola.)
- The change in height compared to the change in time is not constant. (True: the rate of change varies — it increases then decreases, not constant.)

Incorrect choices:
- The data shows an exponential relationship. (False.)
- The data shows a linear relationship. (False.)
- The height will increase over time at a constant rate of change. (False — the rate changes, reaching zero at the peak.)
