Question

question 1
given the scatterplot below.
which regression model would be most appropriate for the data?

• no regression because there is no association.
• linear regression
• exponential regression
• quadratic regression

question 2

Explanation:

The scatterplot shows a U-shaped (curved, parabolic) pattern, where the data points first decrease to a minimum and then increase. This matches the shape of a quadratic function, which models relationships with a single curve (either opening upward or downward). Linear regression is for straight-line relationships, exponential regression is for exponential growth/decay, and there is a clear association present in the data.

Answer:

Quadratic regression
