why are the zeros of cubic functions visible on graphs but not on the data points? How do the differences between real data and the graph of an equation contribute to that?
I'm not really sure how to answer this and I've tried to look up more details on this online with not much of a success. If it helps the data was height and volume of different figures and I had to graph it. Here are some links of the graph and data tables I made from the assignment.

This problem illustrates the difference between what is going on in the real world and the equations that model it (note that they are NOT what is really happening, they are a model of what is really happening). Here the domain of the function (the graph) is limited by reality, not by the math behind the equation.
