Quizplus · Accepted Answer

Using regression feature on a graphing calculator, the quartic function is: 
y = -0.0418x^4 + 1.9749x^3 - 32.4204x^2 + 232.7851x + 1204.0051
Rounding to five decimal places, the function is:
y = -0.04178x^4 + 1.97488x^3 - 32.42043x^2 + 232.78510x + 1204.00507
Therefore, the best choice is D.
