What is the error in the student’s reasoning below? Describe how to correct the statement. Choose answer.
A. The student did not check to ensure that the second differences and common ratios are not also constant. If either is constant, than the dats set is not linear.

B. The student did not check to ensure that the differences between the x-values are constant. Since they are not, the student cannot make a determination about the dats by analyzing the first differences.

C. The student did not check that the second differ are also constant. Since they are, the data is best modeled by a quadratic function.

D. The student did not check that the common ratios are roughly equivalent. Since they are, the dats is best modeled by an exponential function.
