Using a trend curve, you can determine the values of a and b that make the power curve best fit a scatter plot diagram. In most situations, a is greater than 0. When this is the case, the slope of the power curve depends on the value of b, as follows:

  • For b>1, y increases as x increases, and the slope of the power curve increases as x increases.

  • For 0<b<1, y increases as x increases, and the slope of the power ...
