Question

While hiking, Marek throws a rock off a cliff that is roughly 10 meters above a lake. This situation is modeled by the equation h=−4.9t2+10
, with h representing the height in meters and t the time in seconds. If you were to set up a table to determine when the rock hits the water, what would be a reasonable scale for the range?(1 point)

Reason: the rock's height ranges from 10 m down to 0 m, so a 2-meter scale (0,2,4,6,8,10) gives clear, useful tick marks.
