                                       Scale: 50 points
  1. (15 points) Find a such that the function f ( x ) continuous at x = 0
                                            (         π
                                                x sin( )      if x ̸= 0,
                                  f (x) =             x
                                                a             if x = 0.
  2. (10 points) Find the tangent lines to the curve
                                                     2x − 4
                                                y=
