1．（a）Sketch the graph of the curve with equation $$y = | \ln ( 2 x + 5 ) | \quad x > - \frac { 5 } { 2 }$$ On your sketch you should clearly state the equations of any asymptotes and mark the coordinates of points where the curve meets the coordinate axes．
（b）Solve the equation \(| \ln ( 2 x + 5 ) | = \ln 9\)
