A fish swims over the waterfall. The distance y (in feet) that the fish falls is given by the function y=16t2 , where t is the time (in seconds).

See Explanation

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
