Step-by-step explanation:
f(x) is increasing for x > 0.
g(x) is increasing for x < 4.
Both functions are increasing on the open interval (0, 4). It will be graphed with a solid line between 0 and 4, and with open circles at 0 and 4. See the black line on the x-axis of the attachment for an example of such a graph.
