How can you tell if a graph is a continuous function or a discrete function?
The graph of a continuous function will not have any 'breaks' or 'gaps' in it. You can draw it without lifting your pencil or pen. The graph of a discrete function will just be a set of lines.
How do you graph x equals equations Like x equals 7y2?
-- make a list of 20 or 30 small numbers-- one at a time, put each number in place of 'y', and figure out what 'x' is-- mark a point at the pair of numbers you have for (x, y) on the graph-- after a while, you'll start to see the graph take shape, and you can fill in the gaps between the points
What graph has space between possible data values?
A graph that has space between possible data values is typically a bar graph representing discrete data. In this type of graph, each bar stands apart from others, indicating that the categories are distinct and not continuous. Examples include graphs showing the number of students in different grade levels or the number of votes for various candidates. The gaps emphasize that the data points are separate rather than part of a continuous range.
How can a graph be misrepresentative of data?
In many ways: There can be gaps in the axes which will exaggerate changes. With three dimensional pictograms, it is not possible to tell whether the values are related to the actual size or the apparent size of the picture. The first relates to the square and the second to the cube of a variable.
Why are there gaps between adjoining rails?
The gaps are there to allow for expansion and contraction. In cold weather the rails will contract leaving gaps between the rails. In warm weather the rails will expand and the gaps will disappear. The ride in summer or winter probably would not change, because when the gaps disappear, there could be a difference in elevation, but not enough to cause a problem.
