Please help with the following question

1 Given f (x) = =*+x+2 x- - 2x+1 (a) Determine the following: (1) All asymptotes of the function. 11 The co-ordinates of the y and x intercepts. (iii) The open intervals on the x-axis on which f (x ) is increasing and those on which it is decreasing. (iv) The co-ordinates of all maximum and minimum points. (v) The intervals on which f (x) is concaved upwards and those on which it is concaved downwards. (vi) The co-ordinates of all points of inflexion. (21] (b) Use the results of part (a) above to sketch the graph of f (x) . [4]
