Step-by-step explanation:
Given

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time
e.g. Time, t = 4,
The distance is:




Another possible question is to determine the time taken to cover a certain distance
e.g.
Distance, y = 400
This gives:


Divide by 16

Take square roots


Graph b would be my guess!
