Question
An experiment is performed with the goal of determining a simple power law for a
certain physical phenomenon. This power law takes the form:
y = ax".
The point of the experiment is of course to determine the constants a and n. Four
plots are made from the gathered data. In one of those plots, y is plotted against x
directly. In another, the graph shows a plot of y vs. x². The 3rd and 4th graphs are
plots of y vs. x and x*, respectively. These four plots A-D are shown below, along
with best-fit curves that go with the points. What is the correct value of n, according
to these results?
