A. Evaluate the polynomial
y = x3− 5x2 + 6x + 0.55 at x = 1.37.
Use 3-digit arithmetic with chopping. Evaluate the percent relative round-off error.
b. Express y as y = ((x − 5)x + 6)x + 0.55 (this is the same equation). Use again 3-digit arithmetic with chopping. Evaluate the percent relative round-off error and compare with part (a). Make the conclusion about which form of the polynomial is superior.
