Do you expect to have difficulties evaluating this function
at x = 0.577? Try it using 3- and 4-digit arithmetic with
chopping.
4.9 (a) Evaluate the polynomial
y=x' – 7x + 8x – 0.35
at x = 1.37. Use 3-digit arithmetic with chopping. Evaluate
the percent relative error.
(b) Repeat (a) but ex press y as
y= ((x– 7)x + 8)x – 0.35
Evaluate the error and compare with part (a),
