Question

This graph represents the height, y, in feet of a drone x minutes into its flight. Plot a point on the graph that represents when the height of the drone switched from increasing to decreasing.

Answer 1

(13, 20)

Explanation:

From the graph, there are three points at which the height of the drone starts decreasing.

The points are:

• (9, 15)

,

• (13,20)

,

• (18,15)

However, observe that of these points, the only point where the height of the drone switched from increasing to decreasing is (13, 20).

The required point is (13, 20).
