What is the positive domain of the function?
Positive domain is another name for the point from which the x values are positive and not negative.
From the figure, it can be seen that the function ascends and passes through the intersection point with the X-axis (where X is equal to 0) at point 2a.
Therefore, it is possible to understand that from the moment X is greater than 2a, the function is in the domains of positivity.
Therefore, the function is positive when:
2a < x
2a < x
