Question

The height of a baseball hit from a bat is modeled by a quadratic function of time, h(t). What does the second coordinate of the vertex of the quadratic function represent?

Answer 1

The maximum height of the baseball. Hope this helped :) 

Answer 2

the second coordinate of the vertex of quadratic function represents the maximum height of the ball

Explanation:

The height of a baseball hit from a bat is modeled by a quadratic function of time, h(t)

General form of h(t) will be -16x^2 + v(t) + h

v represents initial velocity and h represents initial height

h(t) represents the height of the baseball

h(t) is negative so the height reaches the maximum

vertex (h,k) represents maximum height (k) when time t=h

So the second coordinate of the vertex of quadratic function represents the maximum height of the ball
