“ The graph f(x) has a stationary point when x=1, a point of inflexion when x=3 and a horizontal asymptote y=2. Sketch the graph y=f'X indicating its features at x=1 and at x=3, amd the shape of the graph as x approaches infinity ”
If you're given f(x) then the graph of f'(x) will be 0 at the stationary points, and stationary at the points of inflexion. It'll also be >0 when f(x) is increasing and <0 when f(x) is decreasing.
