Asked by Levi
baseball is hit at a height of 3 feet above the ground. At a horizontal distance of 210 feet from home plate, the ball reaches its maximum height of 60 feet.
a)write a quadratic function to represent the height of the baseball as a function of it's distance from home plate
B)determine the height of the baseball when it is 180 feet from home plate. round the answer to the nearest 10th

The vertex is on the axis of symmetry, so
h(x) = a(x-210)^2 + k
You know that
h(210) = 60, so k=60
h(0) = 3, so that lets you find a
Now use that to answer (b)
h(x) = a(x-210)^2 + k
You know that
h(210) = 60, so k=60
h(0) = 3, so that lets you find a
Now use that to answer (b)
