They are more useful when you are just looking for a range of values or intervals quickly
Draw a vertical line if the line hits more than one point on the graph then it is not a function.
It does not. In fact, it usually contains less information because some of the precision of the data in the table may not be easy to retrieve from the graph. However, many people (but not all) find it easier to get a summarised version of the information from a graph than from a table.
Just as you would draw the graph of any other function: -- Select several different numbers for 'x'. -- For each one, calculate the value of "sin1by x", and mark the point on the graph paper. -- After you've done this for enough values of 'x', you'll start to see the shape of the graph, with whatever twists and turns it may have. From there, you can draw most of it free-hand, without any more calculations.
You use the vertical line test. If you can draw a vertical line though the graph and it intersects it only once, it is a function. If the line crosses the graphs more than once it is not.
Its more accurate
A graph can be more useful for making presentations because it is more visual, and it can be easier to recognize a pattern in a graph for the same reason. However, a graph doesn't have any more data than a table with the same data.
There are a few different things that will make a climate graph more useful. Having data for a long period of time makes this graph very useful.
Reading a table, drawing a graph, drawing a diagram, and writing a equation.
visually.
A graph is similar to a data table in that they both present the data. A difference is that the graph is more of a visual representation. Often, trends in the data are easy to recognize in the visual representation of the graph.
A graph can visually display trends and patterns in the data that may not be as easily discernible from a table. It allows for quick understanding of relationships and comparisons, making it easier to interpret the information and draw conclusions. Graphs can also provide a more intuitive representation of data for those who are visual learners.
Draw a graph of a given curve in the xoy plane. Now draw a vertical line so that it cuts the graph. If the vertical line cuts the graph in more than one ordinate then given graph is not a function. If it cuts the graph at a single ordinate such a graph is a function.(is called vertical line test)
Draw Table ;)
Draw Table Feature
One line can have only one slope. It is possible to draw more than one line on a single graph, however.
