1. The problem statement, all variables and given/known data f(x)= 3+6x-2x^3 (a) Determine the values of x for which the graph of f has positive gradient (b) Find the values of x for which the graph of f has increasing gradient 2. Relevant equations I had originally thought the two terms meant the same thing, but when I checked the answers at the back of the book, they gave two different answers. 3. The attempt at a solution Isn't a positive gradient an increasing one?
