A set of points is collinear if you can draw one line through them all. The word literally means “together on a line.” Two points are always collinear: no matter where you draw the two points, you can always draw a straight line between them. A general way to write this is: “Poi...
However, two subsequences (odd terms and even terms) are convergent, as shown on the following graph: From the graph, we can see that the subsequence of even terms converges to 1, which means that the limit superior = 1. The limit inferior converges from below to -1. These limits give...
Step 5:Draw the curve or line of the graph.This is really just connecting the dots. If you aren’t sure at this point about the shape of the graph, go back to Step 1 and choose a couple more x-values to complete the picture. Step 6:Check your work. You could use a graphing ca...
Step 2:Draw a graph. Put the mean you identified in Step 1 in the center. Put the number associated with “between” on the graph (take a guess at where the numbers would fall–it doesn’t have to be exact). For example, if your mean was $100, and you were asked for “hourly ...
A function takes an input (x) and produces a single output (y) for each x-value. Functions also pass thevertical line test; if you draw a vertical line through the graph of a function, it never intersect the graph more than once. ...
