You throw a basketball whose path can be modeled by y=-16x^2+15x+6, where (in seconds) and y represents height of the basketball (in feet).
A. What is the maximum height that the basketball reaches?
B. And how many seconds will the basketball hit the ground if no one catches it?

we can do this

$$ y=-16x^2+15x+6$$ the maximum height is at the vertex
the first coodinate of the vertex is $-\frac{b}{2a}$ which in this case is$$-\frac{15}{2\times -16}=\frac{15}{32}$$
