Inverting amplifer question
http://img210.imageshack.us/i/electronicsquestionsq30.jpg/

Can do part a) ! Vout/ Vin = -R2 / R1

and found part d) in a book, that closed loop gain is less but more linear and am able to draw the graph.

Any help with b) c) e) f) would be great, particulary part b) and c) as i think its something very basic that i should know!
