Hey, i have this assignment where I need to describe graphs of displacement, velocity and acceleration. The teacher said to use words like "inversly increasing, inversly decreasing, exponentially increasing and exponentially decreasing" Can you give me an overview of describing graphs this way? How do i describe it in words?

These are the three equations of the graphs I have:
