Step-by-step explanation:
The function can be graphed using a graphing calculator, geometry app, or spreadsheet. One such graph is attached. Often, these tools are capable of identifying extrema and intercepts.
__
<h3>extreme</h3>The vertex of the graph is reported as (x, y) = (2, 20). This means the maximum height is reached after 2 seconds. That maximum height is 20 meters.
__
<h3>intercept</h3>The drop is launched from ground level at x = 0 seconds. It returns to ground level at x = 4 seconds.
