What does the derivative of a function mean? Thus if it is positive/negative what does that mean about the function?

Ah right so i need to find the values of x for which the gradient is positive?
Do i just do this by trial and error substituting in x values, or is there something im missing?

You want
If x < 0, then x(x-6) > 0
If 0 < x < 6, then x(x-6) < 0
If x > 6, then x(x-6) > 0
So if , then is positive.
Or in English, except for values of x between 0 and 6, everywhere it is increasing
