2- Consider that the geometry of the billboard for the Pool is following the algebraic equation: y= X^2+4x- 4. It is required to attach two torches for each direction for billboard. The purpose of the torch is to give a clear vision for the cars parking; thus it should not be hanged no more than 7m in height. Accordingly, you have to define in your report the rang of the value of x where the torch could be hanged without violating the maximum allowable height. The billboard width is 6.5m.
