quadratics

a ball os thrown into the air from the roof os a building that is 25 m high. the ball reaches a maximum height of 45 m above the ground after 2 s and hits the ground 5
s after being thrown.

a. use the fact that the realtion between toime and the height of the ball is a quadratic relation to sketch the graph of it.

b. carefully fold the axis of symmetry. extend the short side of the parabola to match the long side.

c. where does the extended graph cross the time axis?

d. what are the zeros of the realtion ?

e. determine the eqation for the relation?

f. determin the coordiantes of the vertex

g. what is the meaning oif each zero?
