Its fall is modelled by the relation h = -4,9t²+342, where h is the height above the ground, in metres, and t is the time after the wrench was dropped in seconds. a) What is the vertex of this relation? b) What does the vertex tell us about the wrench's drop? c) How far has the wrench fallen after 5 seconds? d) When will the wrench hit the ground? What does this point represent on the graph (hint! convert to factored form)
