Ineed answering a quadratic relation word problem.

Check the picture below, that one use feet, but is the same thing, in this case is just centimeters.

a)

so the parabola highest point is at the vertex's y-coordinate, which one will that be?



b)

well, when t = 3, you'll just get h = -4(3)² + 60.

and surely you know what that is.

c)

recall that the x-intercepts occur when y = 0, in this case, when h = 0,
