Hi Tanyanagra,
For me using substitution is better than trying to manipulate the variables, especially under pressure....here's how I solve it !
Substitute x=2 into this 1st equation:f(x) = x divided by x+1 f(2) = 2 divided by 2+1 = 2/3
Then, the question asks what is f(1/x) in terms of f(x)?
You'll need to convert the f(x) to f(1/x) that will be 1/x divided by 1/x+1
Substitute x=2 into this 2nd equation
