Using a quadratic regression calculator, determine the values of a, b, and c that can be used to write a quadratic function that provides a reasonable fit to the set of data. Which of the following statements is true?
A). The coefficient of determination is 0.994, which means that the function is a very good fit of the data set.
B). The coefficient of determination is 0.994, which means that the function is not a very good fit of the data set.
C). The coefficient of determination is 0.035, which means that the function is a very good fit of the data set.
D). The coefficient of determination is 0.035, which means that the function is not a very good fit of the data set.
