A function is graphed.In which entire interval is the function increasing?A 0 to 5B 1 to 3C 2 to 5D 4 to 6

Let's determine which part of the given graph are the given choices be found:
A graph that shows an increasing function must be an inclined line rising from left to right.
Among the given intervals, only the interval B or interval 1 to 3 shows an increasing graph.
Therefore, the answer is letter B.
