Given function : y = -16x^2 + 24x + 1.
Where the height y, in feet, of a football x seconds after it is thrown.
We need to explain what information does the zero of the equation the 6 = -16x^2 + 24x + 1 represents.
We can see that y is being replaced by 6 on left side of the equation.
And y represents the height of the ball after x seconds.
Therefore, correct statement is "when the ball is 6 ft above the ground".
According to the quadratic equation for the ball's height, it is found that the zero of the equation [tex]6 = -16x^2 + 24x + 1[/tex] represents:
- The instant of the time x when the ball is 6 ft above the ground
The height of the ball y(x), after x seconds, is modeled by:
[tex]y(x) = -16x^2 + 24x + 1[/tex]
The equation given is:
[tex]6 = -16x^2 + 24x + 1[/tex]
- In which [tex]y(x) = 6[/tex], hence, the height is of 6 feet above the ground, and the zeroes are the instants of time when the ball is 6 ft above the ground.
