Get answers by asking now. 7 It means inverse of f (x).For function to be invertible it should be bijective i.e. ⋅ | 2 | 3 | 4 | 5 consider a function: f ''(x)=df '(x)/dx =d2(f(x))/dx2 = 3.2.x + 2, where read x3 as x cube , x2 is x square , and in last line is d square f(x) upon d x square.     = setting up to insert the new  input What positive number added to its reciprocal gives the minimum sum?

B b So f(x) shows us the function is called "f", and "x" goes in. And " (f o g) (x) " means " f (g (x))".
