# advice/help? - c3 graph transformations/functions watch

1. Hi, I'm a bit stuck on part b and c of this question

a) express f(x) = 2x+5/x+3 -1/(x+3)(x+2) as a single fraction : i got 2x+3/x+2

b) hence show that f9x) = 2 - 1/x+2, x>-2 : i have no idea where to start with this question!

c) the curve y=1/x, x>0 is mapped onto the curve y=f(x) using 3 successive transformations T1, T2 and T3, where T1 and T3 are translations

describe fully T1, T2, AND T3

For b) you can use a division method e.g. long division if you've learn that?
