Eben, an alien from the planet tellurango, kicks a football from field level. the equation for the football’s height in meters, h, after t seconds is h(t)=−2t2+12t.
what is the maximum height that the ball reaches, assuming nobody blocks the ball? how can you justify your answer.
select the option that correctly answers both questions.
the ball reaches a maximum height of 18 meters. the maximum of h(t) can be found only graphically by plotting the function and locating the y-coordinate of the highest point.
the ball reaches a maximum height of 3 meters. the maximum of h(t) can be found only graphically by plotting the function and locating the x-coordinate of the highest point.
the ball reaches a maximum height of 18 meters. the maximum of h(t) can be found both graphically or algebraically, and lies at (3,18). the x-coordinate, 3, is the time in seconds it takes the ball to reach maximum height, and the y-coordinate, 18, is the max height in meters.
