A table of values gives us:
| t | 0 | 10 | 20 | 30 | 40 | 50 |
| v | 0 | 60.1 | 82.1 | 90.3 | 93.3 | 94.4 |
The sketch is:
If we take larger values of t, the velocity does not go over 95. In this case, the terminal velocity of the object is 95 km/h.
While this looks a bit like the graph of the logarithm function, it is quite different. This one starts at (0, 0), does not pass through (1, 0) and does not increase without bound.
