Procedures

A graph shows the water level in a bathtub over time, in this
order: the level rises steadily for 5 minutes (faucet on), then
stays flat for 10 minutes (no water added or removed), then drops
steadily for 8 minutes (drain pulled). Which sequence correctly
describes this graph using increasing / decreasing / constant?

Decreasing, then constant, then increasing.

Increasing, then constant, then decreasing.

Increasing the whole time, since water is involved throughout.

Constant, then increasing, then constant.
