First decision of choice for general pattern which the graph shows, starting at the green point, is min-mid-max-mid-min. The pattern is that of cosine.
The graph of cosine is the up and down graph similar to the sine graph, but the graph of cosine is symmetric to y-axis and not to the x-axis like sine graph.
The equation for the graph given, which has to be choose for the graph as,
[tex]y = a\cos[b(x - h)] k[/tex]
[tex]y = a\sin[b(x - h)] k[/tex]
The graph for the given pattern shown in the image attached below.
The graph it shows the relationship between the time (in seconds) and height of water (in meters).
The graph shows the up, down pattern. Starting from green point, we get the minimum height of water. Then after some time the water height reached to medium level and then highest.
Again the height reaches to the medium point and then lowest. This pattern is keep on flows for the whole graph.
The graph is symmetric to y-axis. Therefore, it is a cosine graph.
Hence, first decision of choice for general pattern which the graph shows, starting at the green point, is min-mid-max-mid-min. The pattern is that of cosine.
