The question is asking you to find the part of the graph where the curve is greater than zero AND it's rising.
That looks like the interval from x=1.4 to about x=2.75 .
To find where a graph is greater than zero and rising, we identify the intervals where the function's values are positive and where its slope is positive. After analyzing, it appears this occurs from approximately x = 1.4 to x = 2.75. Thus, this range meets both conditions.
