A.4.3.1 Observing a Drone

Here is a graph that represents function f, which gives the height of a drone, in meters, t seconds after it leaves the ground. Decide which function value is greater.

How did you compare f(t) and f(t+1)?

For each pair, what we are comparing are the vertical values (y-value on the graph) of the points on the graph at different horizontal values. Even though the statements don’t tell us the values of, say f(3) and f(7), and the vertical axis shows no scale, we can tell from the graph that the function has a greater value when t is 3 than when t is 7.

The coordinates (0, f(0) represent the starting point of the drone. What are the coordinates of the points when the drone starts leveling off? When it starts to descend (go down)? When it lands? write answers in the form: ( __, f(__))
