As I predicted, I'm well on the way to asking a whole heap of questions about C3. This time I'm having difficult with functions:
a) find h(x)
b) find h^-1
I got h(x) to be 5/(x+2) -2 and x can't equal -2, however I then couldn't do part b) as I kept ending up with either an xy or an x/y when trying to get y by itself.
Thanks in advance
And with hindsight, it's actually really obvious...
Thanks though, fancy sitting the exam with me and pointing out all the things I miss?
