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: h ranges from 0 to 10 m, so a 2-meter scale gives convenient tick marks 0, 2, 4, 6, 8, 10 for the table/graph.
