    if line/curve is above the x-axis the gradient is positive and if the graph is below the gradient is negative
    Sketch according to slope

    So for f'(x) to f"(x)
    Same thing

    Yeah its the same process as sketching f(x) to f'(x).

    - Stationary points become x-intercepts
    - Parts with a positive gradient are above the x axis
    - Parts with a negative gradient are below the x axis
