b) show that the graph of 11 against x passes through the origin'

c) By attempting to find the turning points of the above function, show that there aren't any.

d) Sketch the graph of Y against x.

e) From the resulting sketch, find:

i) The value that y approaches to whenever r increases to a very large number.

ii) The sampling interval T if, as the parameter y increases, x is required to approach the value -2.
