A rock is dropped off a cliff that is 10 meters high into a lake below. (Assume there is no air resistance.) The formula for the height of an object dropped is h (t) = at² + s, where the gravitational constant, a, is -9.8 meters per second squared, s is the initial height, and h (t) is the height in meters modeled as a function of time, t
Which of the following statements are true about the situation and its graph?
Select all that apply.
