12 3 The rate of deflection from a hori- yA (Metres) zontal position of a 3-metre diving (Metres) board when an 80-kg person is x 0 metres from its fixed end is given by Board Deflection dx dy = - 0.03 (x+ 1)2+0.03, where y is the deflection in metres. a What is the deflection when x = 0? b Determine the equation which measures the deflection. c Hence, find the maximum deflection
