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 meters, h, is given by

Well, the general formula for height is h = - 4.9t^2 + v0t + h0, where v0 = starting velocity, and h0 = starting height. This function does technically represent the relationship between the height and the number of seconds it has been in the air.
