Maths and statistics discussion, revision, exam and homework help. 47 Minutes Ago: 21st September 2011 19:32 Ok, consider very small positive values of x and very large positive values of x
What happens to the fraction?hmm when its a very small +ve value the fraction increases, whereas when the value of x increases the answer tends towards 2??

so the minimum point must be 2, and the value of x as it increases towards infinity will tend towards 2

so f(x) > 2?

...and does that stack up with the graph you have drawn....with an asymptote at y = 2?
