Scatter plot showing exponential relationship
Discussion	Note that a simple straight line is grossly inadequate in describing the relationship between X and Y. A quadratic would prove lacking, especially for large values of X. In this example, the large values of X are yielding constant values of Y, and hence a non-linear function beyond the quadratic is needed. Among the many other non-linear functions available, one of the simpler is the exponential model for some A, B, and C. In this case, an exponential function would, in fact, fit well, and hence one is led to the summary conclusion of an exponential relationship.
