Give the maximum number of zeros the polynomial function may have. Use Descarte's Rule of Signs to determine how many positive and how many negative zeros it may have.f(x) = x6 - x5 - x4 - 5x3 + 2x2 + 2x + 3
A. 6; 3 or 1 positive zeros; 3 or 1 negative zeros
B. 6; 2 or 0 positive zeros; 2, or 0 negative zeros
C. 6; 4, 2, or 0 positive zeros; 2 or 0 negative zeros
D. 6; 2 or 0 positive zeros; 4, 2, or 0 negative zeros
Answer: D

Solve.The following data show the relationship between the radius of a sphere and the volume of that sphere. 
a.Plot the ordered pairs (x, y) on a graph and connect the points with straight lines.b. Compute and interpret the average rate of change in volume between radii of 2 and 5feet.c. Compute and interpret the average rate of change in volume between radii of 10 and 12 feet.d. Based upon the results to parts a, b, and c, do you think that the volume of the sphere is linearly related to the radius? Why?
