Prompt
The equation gives the estimated height above ground, y, in meters, of a plane, where x is the number of seconds since it started a parabolic maneuver. If this equation is graphed in the xy-plane, which of the following is the best interpretation of the vertex of the graph?
The plane reached an estimated maximum height of 10,700 meters 4.9 seconds after it started the parabolic maneuver.
A
The plane reached an estimated maximum height of 10,700 meters 9.1 seconds after it started the parabolic maneuver.
B
The plane reached an estimated maximum height of 4.9 meters 10,700 seconds after it started the parabolic maneuver.
C
The plane reached an estimated maximum height of 9.1 meters 10,700 seconds after it started the parabolic maneuver.
