Question

6.4.3 test (cst): data and mathematical modeling
by visual inspection, determine the best - fitting regression model for the scatterplot.
a. quadratic
b. exponential
c. linear
d. no pattern

Explanation:

A quadratic regression model forms a parabolic - like pattern. In the scatterplot, the data points seem to follow a U - shaped or inverted U - shaped (in this case, more of a U - like) pattern which is characteristic of a quadratic relationship. An exponential model would show a rapid increase or decrease (either approaching a horizontal asymptote or growing/shrinking without bound in an exponential way). A linear model would show points that can be approximated by a straight line. Since there is a pattern (not random), option D is incorrect.

Answer:

A. Quadratic
