Question

How can you tell whether a graph shows discrete domain or continuous domain?

Answer 1

A graph which shows a discrete domain is a set of points not connected between them, while a graph which shows a continuous domain is a continuous curve.

Answer 2

Answer:

Well, in order to tell whether a graph shows a discrete or continuous domain, we need to know the difference first. A discrete graph shows only a certain number of input values, like a graph only showing numbers going by 5's. Graphs like these will not connect the plotted points on the graph. A graph with a continuous domain will (like it sounds) show a continuous number of input values (decimals included), and the plotted points would be connected by a line.
