A football is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 64t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?

Question

Ferredoxin4 · Answer

What is axis of symmetry?
AOS:
x=-b/2a of the standard quadratic formula ax^2+bx+c

What does it represent?
AOS is a vertical, x=n line. It would represent something of the independent variable and intercepts the vertex of the function. Here, the independent variable is time. The vertex here is the peak height of the ball. So what do you think the AOS represents?
