Domain and range of a function explained in plain English. Different ways to find the domain and range including graphs, "guess and check".
You can also simply graph the polynomial and make a visual judgement. In the image below, the polynomial has a relative maxima at 2 and relative minima at 4 and -2. The relative minima at -2 is also a global minima; the absolute maxima doesn’t exist because the value of the polynomia...
however I am going to explain how to get it onto a graph and relate it to the O notation of quick sort. As you can see on the graph (which is the output graph I got), there is some white noise going on especially towards the larger datasets, and that is because of the arrangement...
