Question
when trying to find the intervals of where the derivative is positive is it the intervals of where the original graph is above the x axis?

no, it is where the graph is rising.
positive derivative means a positive slope.
It has nothing to do with where the graph is in relation to the x-axis. y can be negative, but still increasing when x increases.
