Question

by visual inspection, determine the best-fitting regression model for the scatterplot.
a. linear
b. no pattern
c. quadratic
d. exponential

Explanation:

The scatterplot shows points that start with a steep decrease in y as x increases, then the rate of decrease slows and approaches a horizontal asymptote. This matches the shape of an exponential decay model, which is characteristic of exponential regression. A linear model would show a straight-line trend, quadratic would form a U or upside-down U, and there is a clear decreasing pattern present.

Answer:

D. Exponential
