The shape of an archway is modelled by the graph ola quadratic lunction. The maximum height of the
archway is 4 m and the maximum width is 4m. The
graph shows a model of the archivay.
a find a lunction in mode the archway
b Use ilie lunction to determine whether an
objec 3 m wide and 1.6 m tall will fit through
the archway.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
