The height h of an arrow in feet is modeled by h(t) = -16t^2 + 63t +4, where t is the time in seconds since the arrow was shot. what is the maximum height of the ball? when will the ball hit the ground? what domain makes sense for the function?

Pretty sure Desmos will help you with this more than anything else, but here goes:

The maximum height reached is 66.016. The ball will hit the ground in 4 seconds. The best domain is -0.063≤x≤4. I'm not too sure about -0.063, it's either -0.063 or -1.

Hope this helps!

Y=3x+1 so the first one
