Question

Which mathematical model is the best fit for the given data, and what is its corresponding R2 value?

A) Linear, R2 = 0.75, good model

B) Exponential, R2 = 0.90, good model

C) Quadratic, R2 = 0.45, not a good model

D) Logarithmic, R2 = 0.60, not a good model

Answer 1

The best fit for the given data is the exponential model, with an R2 value of 0.90.

Step-by-step explanation:

The best fit for the given data is the exponential model, corresponding to option B. The value of R2 for the exponential model is 0.90, which indicates a good model fit.

A higher R2 value closer to 1 suggests that the model explains a larger proportion of the variation in the data.
