You can  put this solution on YOUR website! An arrow is shot into the air, a function representing the relationship between the number of seconds it is in the air, t and the height of the arrow in meter, h, is given by: h(t) = -4.9t^2 + 29.4t + 2.5, what is the maximum height of the arrow ? 
----------- 
It's a parabola. 
The max height is the vertex. 
Do you know how to find that?
